Loading vulnerability…
A race condition exists in the SMB client implementation in Microsoft Windows Server 2008 R2 and Windows 7, which allows remote SMB servers and man-in-the-middle attackers to execute arbitrary code. In Windows Vista (Gold, SP1, SP2) and Server 2008 (Gold, SP2), the same flaw allows local users to gain privileges. The vulnerability is triggered via a crafted SMB Negotiate response, exploiting improper synchronization in the SMB client code.

This repository contains a single Metasploit auxiliary module targeting a denial of service vulnerability (CVE-2010-0017) in the Microsoft Windows 7 and Windows Server 2008 R2 SMB client. The module acts as a malicious SMB server, listening on TCP port 445. When a vulnerable client connects (typically by accessing a crafted UNC path such as \\<attacker_ip>\Shared\Anything), the module sends a specially crafted SMB negotiation response that causes the client to enter an infinite loop, resulting in a denial of service. The exploit is operational and requires the attacker to induce the target to connect to the attacker's SMB server, which can be achieved by embedding the UNC path in a web page or document. The code is written in Ruby and is structured as a standard Metasploit module.
