CVE-2023-41900  (opens in a new tab)
CWE-287  (opens in a new tab)

How to fix?

Upgrade org.eclipse.jetty:jetty-openid to version 9.4.52.v20230823, 10.0.15, 11.0.15 or higher.

Overview

Affected versions of this package are vulnerable to Improper 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.

Impact:

A request on a previously authenticated session could be allowed to bypass authentication after it had been rejected by the LoginService.
