HTTP: Microsoft IIS Directory Security Bypass
This signature detects attempts to exploit a known vulnerability against Microsoft IIS. Attackers can bypass security restrictions on directories enabling them to view, edit, and download information.
Extended Description
Microsoft Internet Information Services (IIS) is prone to an authentication-bypass vulnerability because it fails to properly enforce access restrictions on certain requests to a site that requires authentication. An attacker can exploit this issue to gain unauthorized access to protected resources, which may lead to other attacks. This issue affects IIS 5.1; other 5.x versions may also be affected. Please note that this issue does not affect versions 6.x and 7.x.
