Summary
Keyfactor EJBCA 9 may cache authentication for longer than the configured maximum time (default 30 seconds) after an administrator is removed from its administrator role while holding a valid TLS session. This is insufficient session expiration (CWE-613), so in certain circumstances a former administrator keeps access it should no longer have.
