A privilege escalation vulnerability exists in IBM WebSphere Application Server 7.0.0.0 through 7.0.0.45, 8.0.0.0 through 8.0.0.15, 8.5.0.0 through 8.5.5.17, 9.0.0.0 through 9.0.5.3 when using token-based authentication in an admin request over the SOAP connector. An authenticated, remote attacker can exploit this to gain higher privileges on the system.
