NVD Description

Note: Versions mentioned in the description apply only to the upstream jetty-server package and not the jetty-server package as distributed by SLES. See How to fix? for SLES:15.3 relevant fixed versions and status.

Jetty is a Java based web server and servlet engine. Versions 9.4.21 through 9.4.51, 10.0.15, and 11.0.15 are vulnerable to weak authentication. If a Jetty OpenIdAuthenticator uses the optional nested LoginService, and that LoginService decides to revoke an already authenticated user, then the current request will still treat the user as authenticated. The authentication is then cleared from the session and subsequent requests will not be treated as authenticated. So a request on a previously authenticated session could be allowed to bypass authentication after it had been rejected by the LoginService. This impacts usages of the jetty-openid which have configured a nested LoginService and where that LoginService will is capable of rejecting previously authenticated users. Versions 9.4.52, 10.0.16, and 11.0.16 have a patch for this issue.
