CVE-2017-7656  (opens in a new tab)

How to fix?

Upgrade Debian:10 jetty9 to version 9.2.25-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream jetty9 package and not the jetty9 package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

In Eclipse Jetty, versions 9.2.x and older, 9.3.x (all configurations), and 9.4.x (non-default configuration with RFC2616 compliance enabled), HTTP/0.9 is handled poorly. An HTTP/1 style request line (i.e. method space URI space version) that declares a version of HTTP/0.9 was accepted and treated as a 0.9 request. If deployed behind an intermediary that also accepted and passed through the 0.9 version (but did not act on it), then the response sent could be interpreted by the intermediary as HTTP/1 headers. This could be used to poison the cache if the server allowed the origin client to generate arbitrary content in the response.
