HTTP: Unknown Request Verb
This signature detects an unknown, non-standard HTTP request command verb. This could be an attempt to tunnel another protocol over HTTP.
Extended Description
The mod_proxy_ajp module in the Apache HTTP Server before 2.2.21, when used with mod_proxy_balancer in certain configurations, allows remote attackers to cause a denial of service (temporary "error state" in the backend server) via a malformed HTTP request.
