Description
The vulnerability allows a remote attacker to escalate privileges.
The vulnerability exists due to sensitive information in resource not removed before reuse in JaspiAuthenticator.java when handling certain error or incomplete authentication flows. A remote attacker can trigger a request sequence that leaves residual authentication metadata in ThreadLocal storage to escalate privileges.
A subsequent unprivileged request processed by the same worker thread may inherit residual security roles if a mandatory CallerPrincipalCallback is missing or an exception occurs after a GroupPrincipalCallback has been persisted.
Remediation
Install security update from vendor's website.
