GHSA-9GRJ-J43M-MJQR
Vulnerability from github – Published: 2022-06-24 00:00 – Updated: 2022-12-05 23:37In Jenkins 2.355 and earlier, LTS 2.332.3 and earlier, an observable timing discrepancy on the login form allows distinguishing between login attempts with an invalid username, and login attempts with a valid username and wrong password, when using the Jenkins user database security realm. This allows attackers to determine the validity of attacker-specified usernames.
Login attempts with an invalid username now validate a synthetic password to eliminate the timing discrepancy in Jenkins 2.356, LTS 2.332.4.
