CVE-2021-26296

Severity

7.5

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.

Mitigation

We recommend upgrading to a version of this component that is not vulnerable to this specific issue. Alternatively, if upgrading is not a viable option, this vulnerability can be mitigated by enabling `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
```

Note: If this component is included as a bundled/transitive dependency of another component, there may not be an upgrade path. In this instance, we recommend contacting the maintainers who included the vulnerable package. Alternatively, we recommend investigating alternative components or a potential mitigating control.
