F5 Networks BIG-IP : Eclipse Jetty vulnerability (K21054458)

high Nessus Plugin ID 159886

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

The version of F5 Networks BIG-IP installed on the remote host is prior to 15.1.9 / 16.1.4 / 17.1.1. It is, therefore, affected by a vulnerability as referenced in the K21054458 advisory.

- 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. (CVE-2017-7656)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K21054458.
