GLSA-200705-17 : Apache mod_security: Rule bypass

This script is Copyright (C) 2007-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200705-17
(Apache mod_security: Rule bypass)

Stefan Esser discovered that mod_security processes NULL characters as
terminators in POST requests using the
application/x-www-form-urlencoded encoding type, while other parsers
used in web applications do not.

Impact :

A remote attacker could send a specially crafted POST request, possibly
bypassing the module ruleset and leading to the execution of arbitrary
code in the scope of the web server with the rights of the user running
the web server.

Workaround :

There is no known workaround at this time.

Solution :

All mod_security users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=www-apache/mod_security-2.1.1'

Risk factor :

Medium / CVSS Base Score : 6.8
