HTTP: Microsoft IIS WebDAV Remote Authentication Bypass
This signature detects attempts to exploit a known vulnerability against Microsoft IIS WebDAV. Attackers can bypass access restrictions, gaining access to files or directories without providing authentication credentials.
Extended Description
Microsoft Internet Information Service (IIS) is prone to multiple authentication-bypass vulnerabilities because the application fails to properly enforce access restrictions on certain requests to password-protected WebDAV folders. An attacker can exploit these issues to gain unauthorized access to protected WebDAV resources, which may lead to other attacks. This issue affects IIS 5.0, 5.1, and 6.0.
