Cross-Site Request Forgery (CSRF) vulnerability in Apache MyFaces

CVE-2021-26296 [CVE] [CVE json] [OSV json]

Last updated: 2021-02-19T08:27:26.368Z

Affected

• Apache MyFaces Core from Apache MyFaces Core 2.2 before 2.2.14
• Apache MyFaces Core from Apache MyFaces Core 2.3 before 2.3.8
• Apache MyFaces Core from Apache MyFaces Core 2.3-next before 2.3-next-M5
• Apache MyFaces Core from Apache MyFaces Core 3.0 before 3.0.0

Description

In the default configuration, Apache MyFaces Core versions 2.2.0 to 2.2.13, 2.3.0 to 2.3.7, 2.3-next-M1 to 2.3-next-M4, and 3.0.0-RC1 use cryptographically weak implicit and explicit cross-site request forgery (CSRF) tokens. Due to that limitation, it is possible (although difficult) for an attacker to calculate a future CSRF token value and to use that value to trick a user into executing unwanted actions on an application.
