Privilege Escalation Using _design Documents

CVE-2023-45725 [CVE] [CVE json] [OSV json]

Last updated: 2023-12-13T08:02:15.239Z

Affected

• Apache CouchDB through 3.3.2
• IBM Cloudant before 8413

Description

Design document functions which receive a user http request object may expose authorization or session cookie headers of the user who accesses the document.

These design document functions are:

•   list
•   show
•   rewrite
•   update

An attacker can leak the session component using an HTML-like output, insert the session as an external resource (such as an image), or store the credential in a _local document with an “update” function.

For the attack to succeed the attacker has to be able to insert the design documents into the database, then manipulate a user to access a function from that design document.

Workaround: Avoid using design documents from untrusted sources which may attempt to access or manipulate request object’s headers

Remote Code Execution Vulnerability in Packaging

CVE-2022-24706 [CVE] [CVE json] [OSV json]

Last updated: 2022-04-26T09:18:02.724Z

Affected

• Apache CouchDB from Apache CouchDB through 3.2.1

Description

In Apache CouchDB prior to 3.2.2, an attacker can access an improperly secured default installation without authenticating and gain admin privileges. The CouchDB documentation has always made recommendations for properly securing an installation, including recommending using a firewall in front of all CouchDB installations.

Privilege escalation vulnerability when using HTML attachments

CVE-2021-38295 [CVE] [CVE json] [OSV json]

Last updated: 2021-10-14T16:26:03.894Z

Affected

• Apache CouchDB from Apache CouchDB before 3.1.2
• IBM Cloudant from IBM Cloudant before 8201

Description

In Apache CouchDB, a malicious user with permission to create documents in a database is able to attach a HTML attachment to a document. If a CouchDB admin opens that attachment in a browser, e.g. via the CouchDB admin interface Fauxton, any JavaScript code embedded in that HTML attachment will be executed within the security context of that admin. A similar route is available with the already deprecated _show and _list functionality.

This privilege escalation vulnerability allows an attacker to add or remove data in any database or make configuration changes. This issue affected Apache CouchDB prior to 3.1.2
