The IBM WebSphere Application Server running on the remote host is version 8.0.0.10 prior to 8.0.0.14, 8.5.5.3 prior to 8.5.5.12, or 9.0.0.0 prior to 9.0.0.4. It is, therefore, affected by a privilege escalation vulnerability in the OpenID Connect (OIDC) Trust Association Interceptor (TAI) that is triggered when the com.ibm.websphere.security.InvokeTAIbeforeSSO custom property includes the OIDC TAI class name com.ibm.ws.security.oidc.client.RelyingParty.
An unauthenticated, remote attacker can exploit this to gain elevated privileges.
