GLSA-200705-17 : Apache mod_security: Rule bypass

medium Nessus Plugin ID 25288

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'
