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.

Weakness

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.
