SAML2 Signature Validation Silently Skipped for Cert-less IdP

CVE-2026-68745 [CVE] [CVE json] [OSV json]

Last updated: 2026-08-21T08:21:27.609Z

Affected

  • Apache CloudStack from 4.5.2 through 4.20.3.0
  • Apache CloudStack from 4.21.0.0 through 4.22.1.0

Description

Certificate validation failures in SAML authentication in Apache CloudStack 4.20.3.0 and 4.22.1.0 on all platforms allow a malicious agent to forge a SAML response to the management server. The agent will have to spoof the ip address of the IdP or get an url of its own choosing registered in the management server, after which it can allow logging on with forged signatures.

Users are recommended to upgrade to versions 4.20.3.1 or 4.22.1.1 and above, which fix this issue.

Unauthorised comment creation and disclosure

CVE-2026-66797 [CVE] [CVE json] [OSV json]

Last updated: 2026-08-21T08:21:57.156Z

Affected

  • Apache CloudStack from 4.16.0.0 through 4.20.3.0
  • Apache CloudStack from 4.21.0.0 through 4.22.1.0

Description

Improper access control in CloudStack's annotation functionality allows unauthorized comment creation and disclosure.

The addAnnotation and listAnnotation APIs perform an ownership check when an entity's UUID is specified, but fail to honor its result correctly. This lets any authenticated user write annotations to, and disclose existing annotations/comments on, an entity they don't own by simply supplying its UUID.

This issue affects Apache CloudStack: from 4.15.0.0 through 4.20.3.0 and from 4.21.0.0 through 4.22.1.0.

Users are recommended to upgrade to version 4.20.3.1 or 4.22.1.1 or later, which fixes the issue.

ProjectRole & ProjectRolePermission authorization issue

CVE-2026-66722 [CVE] [CVE json] [OSV json]

Last updated: 2026-08-21T08:22:35.208Z

Affected

  • Apache CloudStack from 4.15.0.0 through 4.20.3.0
  • Apache CloudStack from 4.21.0.0 through 4.22.1.0

Description

Improper authorization for CRUD operations on Project Roles and Project Role permissions for domain admins in CloudStack.

A Domain Admin can create, update, delete, and list project roles and project role permissions for projects in any domain, not just their own. The check only confirms the caller is a Domain Admin, without verifying whether the target project belongs to their domain or subdomain. This allows a malicious Domain Admin to tamper with project roles and permissions across unrelated domains.

This issue affects Apache CloudStack: from 4.15.0.0 through 4.20.3.0 and from 4.21.0.0 through 4.22.1.0.

Users are recommended to upgrade to version 4.20.3.1 or 4.22.1.1 or later, which fixes the issue.

Affected

  • Apache CloudStack from 4.12.0.0 through 4.20.3.0
  • Apache CloudStack from 4.21.0.0 through 4.22.1.0

Description

Missing authorization issue for domain admins in CloudStack's host tags listing functionality.

Domain Admins, by default, have permission to call the listHostTags API, but the API returns host tags for every host in the environment without domain scoping. It should instead be restricted to only the hosts dedicated to that admin's domain.

This issue affects Apache CloudStack: from 4.12.0.0 through 4.20.3.0 and from 4.21.0.0 through 4.22.1.0.

Users are recommended to upgrade to version 4.20.3.1 or 4.22.1.1 or later, which fixes the issue.

Authenticated pre-validation SSRF in registerTemplate

CVE-2026-61422 [CVE] [CVE json] [OSV json]

Last updated: 2026-08-21T08:24:36.997Z

Affected

  • Apache CloudStack at 4.20.3.0
  • Apache CloudStack from 4.21.0.0 through 4.22.1.0

Description

Authenticated pre-validation SSRF vulnerability in Apache CloudStack’s template and ISO registration functionality.

When registering a template or ISO, CloudStack makes a live HTTP HEAD/GET call to determine file size for secondary storage usage-limit checks, and this happens before URL validation is performed. However, this does not pose a malicious template or ISO registration risk, as URL validation still occurs prior to the actual download by the Secondary Storage VM.

This issue affects Apache CloudStack: in 4.20.3.0 and from 4.21.0.0 through 4.22.1.0.

Users are recommended to upgrade to version 4.20.3.1 or 4.22.1.1 or later, which fixes the issue.

Get and Run Diagnostics Command Injection

CVE-2026-61400 [CVE] [CVE json] [OSV json]

Last updated: 2026-08-21T08:25:01.740Z

Affected

  • Apache CloudStack from 4.14.0.0 through 4.20.3.0
  • Apache CloudStack from 4.21.0.0 through 4.22.1.0

Description

Improper Neutralization of Special Elements used in a Command ('Command Injection') vulnerability in Apache CloudStack's run and get diagnostics functionality for the system VMs and virtual routers.

An authenticated user holding the permissions required to invoke either `getDiagnosticsData` or `runDiagnostics` can achieve arbitrary command execution on the system VM and/or Virtual Router instances, with commands running as root (or as the diagnostics-process user, at minimum). This represents a full compromise of the affected instance and, depending on network segmentation, may provide a foothold for lateral movement within the CloudStack-managed infrastructure, including access to guest network traffic handled by the compromised Virtual Router.

The getDiagnosticsData and runDiagnostics APIs are restricted to only Admin role accounts by default.

This issue affects Apache CloudStack: from 4.20.0.0 through 4.20.3.0 and from 4.21.0.0 through 4.22.1.0.

Users are recommended to upgrade to version 4.20.3.1 or 4.22.1.1 or later, which fixes the issue.

RCE and SSRF in direct download, metalink and NFS templates

CVE-2026-50112 [CVE] [CVE json] [OSV json]

Last updated: 2026-08-21T08:29:39.850Z

Affected

  • Apache CloudStack from 4.14.0.0 through 4.20.3.0
  • Apache CloudStack from 4.21.0.0 through 4.22.1.0

Description

SSRF via Metalink Mirror URL Resolution:

An authenticated tenant can register a template pointing to an attacker-controlled metalink file containing internal targets. The Secondary Storage VM will retrieve the data and persist it as a template file, which can later be downloaded through normal APIs.

RCE on KVM hypervisor via NFS, Metalink files with/without Direct Downloads:

An authenticated CloudStack tenant holding the default User role can execute arbitrary shell commands as root on the KVM hypervisor host that runs other tenants' VMs. This is cross-tenant root on the underlying compute, reachable via the public CloudStack API.

When a User registers a VM template with directDownload=true and a URL pointing to a .metalink file, the management server fetches the metalink XML and dispatches download to the KVM agent. Inner URLs inside the metalink XML are never re-validated against the scheme allowlist.

These issues affect Apache CloudStack: from 4.14.0.0 through 4.20.3.0 and from 4.21.0.0 through 4.22.1.0.

Users are recommended to upgrade to version 4.20.3.1 or 4.22.1.1 or later, which fixes the issue.

Proxmox Extension Allows Unauthorized Cross-Tenant Instance Access

CVE-2026-25199 [CVE] [CVE json] [OSV json]

Last updated: 2026-05-08T12:23:04.078Z

Affected

  • Apache CloudStack from 4.21.0 through 4.22.0

Description

Instances deployed via the Proxmox extension allow unauthorized access to instances belonging to other tenants.

This issue affects Apache CloudStack: from 4.21.0.0 through 4.22.0.0.

The Proxmox extension for CloudStack improperly uses a user-editable instance setting, proxmox_vmid, to associate CloudStack instances with Proxmox virtual machines. Because this value is not restricted or validated against tenant ownership and Proxmox VM IDs are predictable, a non-privileged attacker can modify the setting to reference a VM belonging to another account. This allows unauthorized cross-tenant access and enables full control over the targeted VM, including starting, stopping, and destroying the virtual machine.

Users are recommended to upgrade to version 4.22.0.1, which fixes this issue.

As a workaround for the existing installations, editing of the proxmox_vmid instance detail by users can be prevented by adding this detail name to the global configuration parameter - user.vm.denied.details.

Affected

  • Apache CloudStack from 4.11.0 through 4.20.2.0
  • Apache CloudStack from 4.21.0.0 through 4.22.0.0

Description

Account users are allowed by default to register templates to be downloaded directly to the primary storage for deploying instances using the KVM hypervisor. Due to missing file name sanitization, an attacker can register malicious templates to execute arbitrary code on the KVM hosts. This can result in the compromise of resource integrity and confidentiality, data loss, denial of service, and availability of the KVM-based infrastructure managed by CloudStack.

Users are recommended to upgrade to Apache CloudStack versions 4.20.3.0 or 4.22.0.1, or later, which fixes this issue.

CVE-2025-47849 [CVE] [CVE json] [OSV json]

Last updated: 2025-06-11T03:59:42.176Z

Affected

  • Apache CloudStack from 4.10.0 before 4.19.3.0
  • Apache CloudStack from 4.20.0.0 before 4.20.1.0

Description

A privilege escalation vulnerability exists in Apache CloudStack versions 4.10.0.0 through 4.20.0.0 where a malicious Domain Admin user in the ROOT domain can get the API key and secret key of user-accounts of Admin role type in the same domain. This operation is not appropriately restricted and allows the attacker to assume control over higher-privileged user-accounts. A malicious Domain Admin attacker can impersonate an Admin user-account and gain access to sensitive APIs and resources that could result in the compromise of resource integrity and confidentiality, data loss, denial of service, and availability of infrastructure managed by CloudStack.

Users are recommended to upgrade to Apache CloudStack 4.19.3.0 or 4.20.1.0, which fixes the issue with the following:
  • Strict validation on Role Type hierarchy: the caller's role must be equal to or higher than the target user's role. 
  • API privilege comparison: the caller must possess all privileges of the user they are operating on. 
  • Two new domain-level settings (restricted to the default admin): 
     - role.types.allowed.for.operations.on.accounts.of.same.role.type: Defines which role types are allowed to act on users of the same role type. Default: "Admin, DomainAdmin, ResourceAdmin". 
     - allow.operations.on.users.in.same.account: Allows/disallows user operations within the same account. Default: true.

Unauthorised template/ISO list access to the domain/resource admins

CVE-2025-30675 [CVE] [CVE json] [OSV json]

Last updated: 2025-06-11T04:00:06.854Z

Affected

  • Apache CloudStack from 4.0.0 before 4.19.3.0
  • Apache CloudStack from 4.20.0.0 before 4.20.1.0

Description

In Apache CloudStack, a flaw in access control affects the listTemplates and listIsos APIs. A malicious Domain Admin or Resource Admin can exploit this issue by intentionally specifying the 'domainid' parameter along with the 'filter=self' or 'filter=selfexecutable' values. This allows the attacker to gain unauthorized visibility into templates and ISOs under the ROOT domain.
A malicious admin can enumerate and extract metadata of templates and ISOs that belong to unrelated domains, violating isolation boundaries and potentially exposing sensitive or internal configuration details. 
This vulnerability has been fixed by ensuring the domain resolution strictly adheres to the caller's scope rather than defaulting to the ROOT domain.

Affected users are recommended to upgrade to Apache CloudStack 4.19.3.0 or 4.20.1.0.

CKS cluster in project exposes user API keys

CVE-2025-26521 [CVE] [CVE json] [OSV json]

Last updated: 2025-06-11T04:00:17.648Z

Affected

  • Apache CloudStack from 4.17.0.0 before 4.19.3.0
  • Apache CloudStack from 4.20.0.0 before 4.20.1.0

Description

When an Apache CloudStack user-account creates a CKS-based Kubernetes cluster in a project, the API key and the secret key of the ‘kubeadmin’ user of the caller account are used to create the secret config in the CKS-based Kubernetes cluster. A member of the project who can access the CKS-based Kubernetes cluster, can also access the API key and secret key of the ‘kubeadmin’ user of the CKS cluster’s creator’s account. An attacker who’s a member of the project can exploit this to impersonate and perform privileged actions that can result in complete compromise of the confidentiality, integrity, and availability of resources owned by the creator’s account.

CKS users are recommended to upgrade to version 4.19.3.0 or 4.20.1.0, which fixes this issue.

Updating Existing Kubernetes Clusters in Projects

A service account should be created for each project to provide limited access specifically for Kubernetes cluster providers and autoscaling. Follow the steps below to create a new service account, update the secret inside the cluster, and regenerate existing API and service keys:

1. Create a New Service Account

Create a new account using the role “Project Kubernetes Service Role” with the following details:
Account Name
kubeadmin-<FIRST_EIGHT_CHARACTERS_OF_PROJECT_ID>
First Name
Kubernetes
Last Name
Service User
Account Type
0 (Normal User)
Role ID
<ID_OF_SERVICE_ROLE>

2. Add the Service Account to the Project

Add this account to the project where the Kubernetes cluster(s) are hosted.

3. Generate API and Secret Keys

Generate API Key and Secret Key for the default user of this account.

4. Update the CloudStack Secret in the Kubernetes Cluster

Create a temporary file /tmp/cloud-config with the following data:
   api-url = <API_URL>     # For example: <MS_URL>/client/api
  api-key = <SERVICE_USER_API_KEY>
  secret-key = <SERVICE_USER_SECRET_KEY>
  project-id = <PROJECT_ID>

Delete the existing secret using kubectl and Kubernetes cluster config:
   ./kubectl –kubeconfig kube.conf -n kube-system delete secret cloudstack-secret

Create a new secret using kubectl and Kubernetes cluster config:
    ./kubectl –kubeconfig kube.conf -n kube-system create secret generic cloudstack-secret –from-file=/tmp/cloud-config

Remove the temporary file:
    rm /tmp/cloud-config

5. Regenerate API and Secret Keys

Regenerate the API and secret keys for the original user account that was used to create the Kubernetes cluster.

Unauthorised access to dedicated resources in Quota plugin

CVE-2025-22829 [CVE] [CVE json] [OSV json]

Last updated: 2025-06-11T04:00:28.410Z

Affected

  • Apache CloudStack from 4.20.0.0 before 4.20.1.0

Description

The CloudStack Quota plugin has an improper privilege management logic in version 4.20.0.0. Anyone with authenticated user-account access in CloudStack 4.20.0.0 environments, where this plugin is enabled and have access to specific APIs can enable or disable reception of quota-related emails for any account in the environment and list their configurations.

Quota plugin users using CloudStack 4.20.0.0 are recommended to upgrade to CloudStack version 4.20.1.0, which fixes this issue.

Unauthorised access to annotations

CVE-2025-22828 [CVE] [CVE json] [OSV json]

Last updated: 2025-01-13T12:40:18.771Z

Affected

  • Apache CloudStack from 4.16.0 through *

Description

CloudStack users can add and read comments (annotations) on resources they are authorised to access. 
Due to an access validation issue that affects Apache CloudStack versions from 4.16.0, users who have access, prior access or knowledge of resource UUIDs can list and add comments (annotations) to such resources. 
An attacker with a user-account and access or prior knowledge of resource UUIDs may exploit this issue to read contents of the comments (annotations) or add malicious comments (annotations) to such resources. 
This may cause potential loss of confidentiality of CloudStack environments and resources if the comments (annotations) contain any privileged information. However, guessing or brute-forcing resource UUIDs are generally hard to impossible and access to listing or adding comments isn't same as access to CloudStack resources, making this issue of very low severity and general low impact.

CloudStack admins may also disallow listAnnotations and addAnnotation API access to non-admin roles in their environment as an interim measure.

Directly downloaded templates can be used to abuse KVM-based infrastructure

CVE-2024-50386 [CVE] [CVE json] [OSV json]

Last updated: 2024-11-12T13:52:37.947Z

Affected

  • Apache CloudStack from 4.0.0 through 4.18.2.4
  • Apache CloudStack from 4.19.0.0 through 4.19.1.2

Description

Account users in Apache CloudStack by default are allowed to register templates to be downloaded directly to the primary storage for deploying instances. Due to missing validation checks for KVM-compatible templates in CloudStack 4.0.0 through 4.18.2.4 and 4.19.0.0 through 4.19.1.2, an attacker that can register templates, can use them to deploy malicious instances on KVM-based environments and exploit this to gain access to the host filesystems that could result in the compromise of resource integrity and confidentiality, data loss, denial of service, and availability of KVM-based infrastructure managed by CloudStack.


Users are recommended to upgrade to Apache CloudStack 4.18.2.5 or 4.19.1.3, or later, which addresses this issue.

Additionally, all user-registered KVM-compatible templates can be scanned and checked that they are flat files that should not be using any additional or unnecessary features. For example, operators can run the following command on their file-based primary storage(s) and inspect the output. An empty output for the disk being validated means it has no references to the host filesystems; on the other hand, if the output for the disk being validated is not empty, it might indicate a compromised disk. However, bear in mind that (i) volumes created from templates will have references for the templates at first and (ii) volumes can be consolidated while migrating, losing their references to the templates. Therefore, the command execution for the primary storages can show both false positives and false negatives.
for file in $(find /path/to/storage/ -type f -regex [a-f0-9-].); do echo “Retrieving file [$file] info. If the output is not empty, that might indicate a compromised disk; check it carefully.”; qemu-img info -U $file | grep file: ; printf “\n\n”; done

For checking the whole template/volume features of each disk, operators can run the following command:
for file in $(find /path/to/storage/ -type f -regex [a-f0-9-].); do echo “Retrieving file [$file] info.”; qemu-img info -U $file; printf “\n\n”; done

Incomplete session invalidation on web interface logout

CVE-2024-45462 [CVE] [CVE json] [OSV json]

Last updated: 2024-10-16T10:39:03.528Z

Affected

  • Apache CloudStack from 4.15.1.0 through 4.18.2.3
  • Apache CloudStack from 4.19.0.0 through 4.19.1.1

Description

The logout operation in the CloudStack web interface does not expire the user session completely which is valid until expiry by time or restart of the backend service. An attacker that has access to a user's browser can use an unexpired session to gain access to resources owned by the logged out user account. This issue affects Apache CloudStack from 4.15.1.0 through 4.18.2.3; and from 4.19.0.0 through 4.19.1.1.

Users are recommended to upgrade to Apache CloudStack 4.18.2.4 or 4.19.1.2, or later, which addresses this issue.

Access checks not enforced in Quota

CVE-2024-45461 [CVE] [CVE json] [OSV json]

Last updated: 2025-02-12T09:30:16.539Z

Affected

  • Apache CloudStack Quota plugin from 4.7.0 through 4.18.2.3
  • Apache CloudStack Quota plugin from 4.19.0.0 through 4.19.1.1

Description

The CloudStack Quota feature allows cloud administrators to implement a quota or usage limit system for cloud resources, and is disabled by default. In environments where the feature is enabled, due to missing access check enforcements, non-administrative CloudStack user accounts are able to access and modify quota-related configurations and data. This issue affects Apache CloudStack from 4.7.0 through 4.18.2.3; and from 4.19.0.0 through 4.19.1.1, where the Quota feature is enabled.

Users are recommended to upgrade to Apache CloudStack 4.18.2.4 or 4.19.1.2, or later, which addresses this issue. Alternatively, users that do not use the Quota feature are advised to disabled the plugin by setting the global setting "quota.enable.service" to "false".

Uploaded and registered templates and volumes can be used to abuse KVM-based infrastructure

CVE-2024-45219 [CVE] [CVE json] [OSV json]

Last updated: 2024-10-15T18:32:48.536Z

Affected

  • Apache CloudStack from 4.0.0 through 4.18.2.3
  • Apache CloudStack from 4.19.0.0 through 4.19.1.1

Description

Account users in Apache CloudStack by default are allowed to upload and register templates for deploying instances and volumes for attaching them as data disks to their existing instances. Due to missing validation checks for KVM-compatible templates or volumes in CloudStack 4.0.0 through 4.18.2.3 and 4.19.0.0 through 4.19.1.1, an attacker that can upload or register templates and volumes, can use them to deploy malicious instances or attach uploaded volumes to their existing instances on KVM-based environments and exploit this to gain access to the host filesystems that could result in the compromise of resource integrity and confidentiality, data loss, denial of service, and availability of KVM-based infrastructure managed by CloudStack.


Users are recommended to upgrade to Apache CloudStack 4.18.2.4 or 4.19.1.2, or later, which addresses this issue.

Additionally, all user-uploaded or registered KVM-compatible templates and volumes can be scanned and checked that they are flat files that should not be using any additional or unnecessary features. For example, operators can run this on their secondary storage(s) and inspect output. An empty output for the disk being validated means it has no references to the host filesystems; on the other hand, if the output for the disk being validated is not empty, it might indicate a compromised disk.
for file in $(find /path/to/storage/ -type f -regex [a-f0-9-].); do echo “Retrieving file [$file] info. If the output is not empty, that might indicate a compromised disk; check it carefully.”; qemu-img info -U $file | grep file: ; printf “\n\n”; done

User Key Exposure to Domain Admins

CVE-2024-42062 [CVE] [CVE json] [OSV json]

Last updated: 2024-08-19T13:43:36.243Z

Affected

  • Apache CloudStack from 4.10.0 through 4.18.2.2
  • Apache CloudStack from 4.19.0.0 through 4.19.1.0

Description

CloudStack account-users by default use username and password based authentication for API and UI access. Account-users can generate and register randomised API and secret keys and use them for the purpose of API-based automation and integrations. Due to an access permission validation issue that affects Apache CloudStack versions 4.10.0 up to 4.19.1.0, domain admin accounts were found to be able to query all registered account-users API and secret keys in an environment, including that of a root admin. An attacker who has domain admin access can exploit this to gain root admin and other-account privileges and perform malicious operations that can result in compromise of resources integrity and confidentiality, data loss, denial of service and availability of CloudStack managed infrastructure.

Users are recommended to upgrade to Apache CloudStack 4.18.2.3 or 4.19.1.1, or later, which addresses this issue. Additionally, all account-user API and secret keys should be regenerated.

SAML Signature Exclusion

CVE-2024-41107 [CVE] [CVE json] [OSV json]

Last updated: 2024-07-19T10:11:15.224Z

Affected

  • Apache CloudStack from 4.5.0 through 4.18.2.1
  • Apache CloudStack from 4.19.0.0 through 4.19.0.2

Description

The CloudStack SAML authentication (disabled by default) does not enforce signature check. In CloudStack environments where SAML authentication is enabled, an attacker that initiates CloudStack SAML single sign-on authentication can bypass SAML authentication by submitting a spoofed SAML response with no signature and known or guessed username and other user details of a SAML-enabled CloudStack user-account. In such environments, this can result in a complete compromise of the resources owned and/or accessible by a SAML enabled user-account.

Affected users are recommended to disable the SAML authentication plugin by setting the "saml2.enabled" global setting to "false", or upgrade to version 4.18.2.2, 4.19.1.0 or later, which addresses this issue.

Integration API service uses dynamic port when disabled

CVE-2024-39864 [CVE] [CVE json] [OSV json]

Last updated: 2024-07-05T13:39:23.006Z

Affected

  • Apache CloudStack from 4.0.0 through 4.18.2.0
  • Apache CloudStack from 4.19.0.0 through 4.19.0.1

Description

The CloudStack integration API service allows running its unauthenticated API server (usually on port 8096 when configured and enabled via integration.api.port global setting) for internal portal integrations and for testing purposes. By default, the integration API service port is disabled and is considered disabled when integration.api.port is set to 0 or negative. Due to an improper initialisation logic, the integration API service would listen on a random port when its port value is set to 0 (default value). An attacker that can access the CloudStack management network could scan and find the randomised integration API service port and exploit it to perform unauthorised administrative actions and perform remote code execution on CloudStack managed hosts and result in complete compromise of the confidentiality, integrity, and availability of CloudStack managed infrastructure.

Users are recommended to restrict the network access on the CloudStack management server hosts to only essential ports. Users are recommended to upgrade to version 4.18.2.1, 4.19.0.2 or later, which addresses this issue.

Unauthenticated cluster service port leads to remote execution

CVE-2024-38346 [CVE] [CVE json] [OSV json]

Last updated: 2024-07-05T13:39:11.185Z

Affected

  • Apache CloudStack from 4.0.0 through 4.18.2.0
  • Apache CloudStack from 4.19.0.0 through 4.19.0.1

Description

The CloudStack cluster service runs on unauthenticated port (default 9090) that can be misused to run arbitrary commands on targeted hypervisors and CloudStack management server hosts. Some of these commands were found to have command injection vulnerabilities that can result in arbitrary code execution via agents on the hosts that may run as a privileged user. An attacker that can reach the cluster service on the unauthenticated port (default 9090), can exploit this to perform remote code execution on CloudStack managed hosts and result in complete compromise of the confidentiality, integrity, and availability of CloudStack managed infrastructure.


Users are recommended to restrict the network access to the cluster service port (default 9090) on a CloudStack management server host to only its peer CloudStack management server hosts. Users are recommended to upgrade to version 4.18.2.1, 4.19.0.2 or later, which addresses this issue.

The extraconfig feature can be abused to load hypervisor resources on a VM instance

CVE-2024-29008 [CVE] [CVE json] [OSV json]

Last updated: 2024-04-04T10:58:44.745Z

Affected

  • Apache CloudStack from 4.14.0.0 through 4.18.1.0, 4.19.0.0

Description

A problem has been identified in the CloudStack additional VM configuration (extraconfig) feature which can be misused by anyone who has privilege to deploy a VM instance or configure settings of an already deployed VM instance, to configure additional VM configuration even when the feature is not explicitly enabled by the administrator. In a KVM based CloudStack environment, an attacker can exploit this issue to attach host devices such as storage disks, and PCI and USB devices such as network adapters and GPUs, in a regular VM instance that can be further exploited to gain access to the underlying network and storage infrastructure resources, and access any VM instance disks on the local storage.

Users are advised to upgrade to version 4.18.1.1 or 4.19.0.1, which fixes this issue.

Affected

  • Apache CloudStack from 4.11.0.0 through 4.18.1.0, 4.19.0.0

Description

By default the CloudStack management server honours the x-forwarded-for HTTP header and logs it as the source IP of an API request. This could lead to authentication bypass and other operational problems should an attacker decide to spoof their IP address this way. Users are recommended to upgrade to CloudStack version 4.18.1.1 or 4.19.0.1, which fixes this issue.

Apache CloudStack SAML Single Sign-On XXE

CVE-2022-35741 [CVE] [CVE json] [OSV json]

Last updated: 2022-07-18T14:26:13.768Z

Affected

  • Apache CloudStack from 4.5.0 before Apache CloudStack*

Description

Apache CloudStack version 4.5.0 and later has a SAML 2.0 authentication Service Provider plugin which is found to be vulnerable to XML external entity (XXE) injection. This plugin is not enabled by default and the attacker would require that this plugin be enabled to exploit the vulnerability. When the SAML 2.0 plugin is enabled in affected versions of Apache CloudStack could potentially allow the exploitation of XXE vulnerabilities. The SAML 2.0 messages constructed during the authentication flow in Apache CloudStack are XML-based and the XML data is parsed by various standard libraries that are now understood to be vulnerable to XXE injection attacks such as arbitrary file reading, possible denial of service, server-side request forgery (SSRF) on the CloudStack management server.

Apache Cloudstack insecure random number generation affects project email invitation

CVE-2022-26779 [CVE] [CVE json] [OSV json]

Last updated: 2022-07-13T11:28:52.383Z

Affected

  • Apache CloudStack from Apache CloudStack before 4.16.1

Description

Apache CloudStack prior to 4.16.1.0 used insecure random number generation for project invitation tokens. If a project invite is created based only on an email address, a random token is generated. An attacker with knowledge of the project ID and the fact that the invite is sent, could generate time deterministic tokens and brute force attempt to use them prior to the legitimate receiver accepting the invite. This feature is not enabled by default, the attacker is required to know or guess the project ID for the invite in addition to the invitation token, and the attacker would need to be an existing authorized user of CloudStack.
