Descriptions

By sending a specially crafted HTTP GET request to a listening Rapid7 Metasploit HTTP handler, an attacker can register an arbitrary regular expression. When evaluated, this malicious handler can either prevent new HTTP handler sessions from being established, or cause a resource exhaustion on the Metasploit server.

Mediante el envío de una petición GET HTTP especialmente diseñada hacia un manejador HTTP de Rapid7 Metasploit que esté escuchando, un atacante puede registrar una expresión regular arbitraria. Cuando se evalúa, este manejador malicioso puede impedir que sean establecidas nuevas sesiones del manejador HTTP o causar un agotamiento de recursos en el servidor de Metasploit
