Rapid7 Metasploit Framework: server-side request forgery

Metasploit Framework versions before 6.5.7 allow HTTP requests made through send_request_cgi! to follow redirects to a different host without restricting the redirect destination. A malicious HTTP server can cause the system running Metasploit to make requests to arbitrary HTTP services reachable from the operator's network, including internal services that are not otherwise accessible to the attacker.
