Class CSRFExclusionImpl

java.lang.Object

hudson.security.csrf.CrumbExclusion

org.jenkinsci.plugins.gitserver.CSRFExclusionImpl

All Implemented Interfaces:

ExtensionPoint

@Extension
public class CSRFExclusionImpl
extends CrumbExclusion

CSRF exclusion for git-upload-pack.

We do some basic checks to significantly limit the scope of exclusion, but because of the dynamic nature of the URL structure, this doesn't guarantee that we have no leak. So to further protect Jenkins, we pass through a fake HttpServletRequest that masks the values of the submission.

If the fake request is routed to HttpGitRepository, which is the only legitimate destination of the request, we'll unwrap this fake request and pass the real request to JGit.

In this way, even if an attacker manages to route the request to elsewhere in Jenkins, that request will not be interpreted as a POST request.
