GHSA-2VVR-5757-QP87

Vulnerability from github – Published: 2022-05-24 19:06 – Updated: 2023-10-27 15:34

Summary

Open redirect vulnerability in Jenkins CAS Plugin

Details

Jenkins CAS Plugin 1.6.0 and earlier improperly determines that a redirect URL after login is legitimately pointing to Jenkins.

This allows attackers to perform phishing attacks by having users go to a Jenkins URL that will forward them to a different site after successful authentication.

Jenkins CAS Plugin 1.6.1 only redirects to relative (Jenkins) URLs.

Severity ?

6.1 (Medium)
