An unspecified vulnerability in Microsoft Internet Information Services (IIS) 5.1 on Windows XP SP3, when directory-based Basic Authentication is enabled, allows remote attackers to bypass intended access restrictions and execute ASP files via a crafted request. This is referred to as the 'Directory Authentication Bypass Vulnerability.' The flaw is triggered by improper enforcement of authentication controls on ASP files within directories protected by Basic Authentication, allowing unauthorized access and execution.

This repository contains a single Metasploit auxiliary module (modules/auxiliary/admin/http/iis_auth_bypass.rb) targeting Microsoft IIS 5.x servers. The module exploits CVE-2010-2731, an authentication bypass vulnerability, by appending the NTFS alternate data stream string ':$i30:$INDEX_ALLOCATION' to the directory path in HTTP requests. This manipulation allows an attacker to bypass basic authentication on protected directories. The module checks if basic authentication is enabled, attempts the bypass, and reports if the attack is successful. The exploit is operational and does not deliver a shell or code execution, but provides unauthorized access to protected resources. The only fingerprintable endpoint is the manipulated HTTP path used in the attack.
