New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

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.
