Scan for poorly configured reverse proxy servers. By default, this module attempts to force the server to make a request with an invalid domain name. Then, if the bypass is successful, the server will look it up and of course fail, then responding with a status code 502. A baseline status code is always established and if that baseline matches your test status code, the injection attempt does not occur. "set VERBOSE true" if you are paranoid and want to catch potential false negatives. Works best against Apache and mod_rewrite.

It was discovered that the Apache HTTP Server did not properly validate the request URI for proxied requests. In certain configurations, if a reverse proxy used the ProxyPassMatch directive, or if it used the RewriteRule directive with the proxy flag, a remote attacker could make the proxy connect to an arbitrary server, possibly disclosing sensitive information from internal web servers not directly accessible to the attacker.

85672817e23c25e72bd6c9922fb22ec525d83fee8b06bd7f90f95794e0e9561dUbuntu Security Notice 1259-1 - It was discovered that the mod_proxy module in Apache did not properly interact with the RewriteRule and ProxyPassMatch pattern matches in the configuration of a reverse proxy. This could allow remote attackers to contact internal webservers behind the proxy that were not intended for external exposure. Stefano Nichele discovered that the mod_proxy_ajp module in Apache when used with mod_proxy_balancer in certain configurations could allow remote attackers to cause a denial of service via a malformed HTTP request. Various other issues were also addressed.

38d5d3cdd137a8ddd27f61f26b4d6bd80a8be345b51f7fcd45471eb5bb0f29baRed Hat Security Advisory 2011-1391-01 - The Apache HTTP Server is a popular web server. It was discovered that the Apache HTTP Server did not properly validate the request URI for proxied requests. In certain configurations, if a reverse proxy used the ProxyPassMatch directive, or if it used the RewriteRule directive with the proxy flag, a remote attacker could make the proxy connect to an arbitrary server, possibly disclosing sensitive information from internal web servers not directly accessible to the attacker. It was discovered that mod_proxy_ajp incorrectly returned an "Internal Server Error" response when processing certain malformed HTTP requests, which caused the back-end server to be marked as failed in configurations where mod_proxy was used in load balancer mode. A remote attacker could cause mod_proxy to not send requests to back-end AJP servers for the retry timeout period or until all back-end servers were marked as failed.
fa52da6f043cacb48e73017394b763ecd084cb2327279a656bc387db875101fcThe 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. This is a proof of concept exploit that demonstrates this vulnerability.
