In Eclipse Jetty, HttpClient may receive a redirect of the form: If an attacker is able to control the redirects, then HttpClient matches authentication credentials against rather than normalizing the path to , and will therefore follow the redirect sending the header for to . This also mean that the attacker must have an evil application deployed on the same domain as the target.

Grounded briefings

Catalog interpretations for three audiences. Each brief cites ingested metadata and the original advisories below. They are not independent research and they do not invent exploit steps.
