What fixes it
No source in this snapshot names a fixed version. The vendor advisories under References are the place to check.
Description
In Eclipse Jetty, HttpClient may receive a redirect of the form:
/secure/../evil
If an attacker is able to control the redirects, then HttpClient matches authentication credentials against /secure rather than normalizing the path to /evil, and will therefore follow the redirect sending the Authorization header for /secure to /evil.
This also mean that the attacker must have an evil application deployed on the same domain as the target.
