Descriptions

IIS 5 and 5.1 supporting WebDAV methods allows remote attackers to determine the internal IP address of the system (which may be obscured by NAT) via (1) a PROPFIND HTTP request with a blank Host header, which leaks the address in an HREF property in a 207 Multi-Status response, or (2) via the WRITE or MKCOL method, which leaks the IP in the Location server header.

Collect any leaked internal IPs by requesting commonly redirected locations from IIS. CVE-2000-0649 references IIS 5.1 (win2k, XP) and older. However, in newer servers such as IIS 7+, this occurs when the alternateHostName is not set or misconfigured. Also collects internal IPs leaked from the PROPFIND method in certain IIS versions.
