Synopsis

The version of Apache HTTP Server running on the remote host is affected by 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 allows a remote attacker to indirectly send requests to intranet servers.Solution
Upgrade to Apache httpd 2.2.22 or later.See Also
