QID 982237

QID 982237: Java (maven) Security Update for org.apache.myfaces.core:myfaces-core-module (GHSA-gq67-pp9w-43gp)

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.

Mitigation:
Existing web.xml configuration parameters can be used to direct
MyFaces to use SecureRandom for CSRF token generation:

org.apache.myfaces.RANDOM_KEY_IN_VIEW_STATE_SESSION_TOKEN=secureRandom
org.apache.myfaces.RANDOM_KEY_IN_CSRF_SESSION_TOKEN=secureRandom
org.apache.myfaces.RANDOM_KEY_IN_WEBSOCKET_SESSION_TOKEN=secureRandom

Successful exploitation of this vulnerability may affect the confidentiality, integrity, and availability of the targeted user.

CVSS V3 rated as High - 7.5 severity.

CVSS V2 rated as Medium - 5.1 severity.
