CVE-2022-43421

CVE-2022-43421: Jenkins Tuleap Git Branch Source Plugin allows unauthenticated attackers to trigger Tuleap projects whose configured repo matches attacker-specified value

A missing permission check in Jenkins Tuleap Git Branch Source Plugin 3.2.4 and earlier allows unauthenticated attackers to trigger Tuleap projects whose configured repository matches the attacker-specified value. Tuleap Git Branch Source Plugin 3.2.5 requires a token to access the webhook endpoint.

Root Cause Analysis

The vulnerability centers around an unauthenticated webhook endpoint at /tuleap-hook/. In Jenkins plugin architecture:

Webhook endpoints are typically handled by doIndex() methods in Stapler-routed classes
The advisory explicitly mentions the endpoint was accessible without authentication
The patch added token validation, which would be implemented in the request handler method
The class name follows Jenkins+Tuleap naming conventions observed in other plugins While no actual code diff is provided, the endpoint behavior described matches the pattern of missing security checks in a request handling method.
