What it is

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.
