CVE-2023-41900: Bring back some openid improvements from 10.0.x to 9.4.x by lachlan-roberts · Pull Request #9660 · eclipse/jetty.project
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.
bring back some openid improvements from recent commits to 10.0.x
Development in OpenID has been progressing on 10+ but not many of the changes have been brought back to 9.4. So this brings back some minimal changes.
This brings back testing for the nested login service and using Instant instead of System.currentTimeMillis for time calculations as well as the improved OpenIdProvider test class.

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.
