Apache HTTP Server mod_proxy Reverse Proxy HTTP 0.9 Information Disclosure

medium Nessus Plugin ID 57875

Language:

Synopsis

The web server running on the remote host has an information disclosure vulnerability.

Description

The version of Apache HTTP Server running on the remote host has an information disclosure vulnerability. When configured as a reverse proxy, improper use of the RewriteRule and ProxyPassMatch directives could cause the web server to proxy requests to arbitrary hosts. This could allow a remote attacker to indirectly send requests to intranet servers by making specially crafted HTTP 0.9 requests.

This vulnerability only affects versions 2.2.x before 2.2.18 that have backported the fix for CVE-2011-3368.

Solution

Contact the distro/vendor for the latest update of Apache httpd.
