An issue was discovered in Cloud Foundry Foundation Cloud Foundry release v252 and earlier versions, UAA stand-alone release v2.0.0 - v2.7.4.12 & v3.0.0 - v3.11.0, and UAA bosh release v26 & earlier versions. UAA is vulnerable to session fixation when configured to authenticate against external SAML or OpenID Connect based identity providers.
Authenticating a user, or otherwise establishing a new user session, without invalidating any existing session identifier gives an attacker the opportunity to steal authenticated sessions.
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Cloud_foundry_cf-release | Pivotal_software | * | 252 (including) |
| Cloud_foundry_uaa | Pivotal_software | 2.0.0 (including) | 2.7.4.12 (including) |

| Cloud_foundry_uaa-release | Pivotal_software | * | 26 (including) |
Such a scenario is commonly observed when:
In the generic exploit of session fixation vulnerabilities, an attacker creates a new session on a web application and records the associated session identifier. The attacker then causes the victim to associate, and possibly authenticate, against the server using that session identifier, giving the attacker access to the user’s account through the active session.
