Root Cause Analysis
The advisory explicitly mentions two critical flaws: 1) Missing permission checks on form validation
methods, and 2) CSRF vulnerability due to lack of POST
requirement. In Jenkins
plugin architecture, form validation
is typically handled by 'doCheck*' methods in DescriptorImpl
classes. The credential ID parameter handling and URL
validation
would logically reside in these methods. The combination of missing CSRF tokens (GET
instead of POST
) and absent permission checks in these validation
endpoints aligns with the described attack vector where attackers manipulate these parameters to exfiltrate credentials.
