CWE-20  (opens in a new tab)

How to fix?

Upgrade Centos:6 httpd to version 0:2.2.15-9.el6_1.3 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream httpd package and not the httpd package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

The mod_proxy module in the Apache HTTP Server 1.3.x through 1.3.42, 2.0.x through 2.0.64, and 2.2.x through 2.2.21 does not properly interact with use of (1) RewriteRule and (2) ProxyPassMatch pattern matches for configuration of a reverse proxy, which allows remote attackers to send requests to intranet servers via a malformed URI containing an initial @ (at sign) character.
