CVE-2022-2047

Description

URI use within Jetty's HttpURI class can parse invalid URIs such as http://localhost;/path as having an authority with a host of localhost;.

A URIs of the type http://localhost;/path should be interpreted to be either invalid or as localhost; to be the userinfo and no host. However, HttpURI.host returns localhost; which is definitely wrong.

Impact

This can lead to errors with Jetty's HttpClient, and Jetty's ProxyServlet / AsyncProxyServlet / AsyncMiddleManServlet wrongly interpreting an authority with no host as one with a host.

Patches

Patched in PR #8146 for Jetty version 9.4.47. Patched in PR #8014 for Jetty versions 10.0.10, and 11.0.10

Workarounds

None.
