A vulnerability, which was classified as critical, has been found in Microsoft IIS up to 6.0 (Web Server). Affected by this issue is an unknown function of the file asp:.jpg. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Microsoft Internet Information Services (IIS), when used in conjunction with unspecified third-party upload applications, allows remote attackers to create empty files with arbitrary extensions via a filename containing an initial extension followed by a : (colon) and a safe extension, as demonstrated by an upload of a .asp:.jpg file that results in creation of an empty .asp file, related to support for the NTFS Alternate Data Streams (ADS) filename syntax. NOTE: it could be argued that this is a vulnerability in the third-party product, not IIS, because the third-party product should be applying its extension restrictions to the portion of the filename before the colon.

The weakness was presented 12/29/2009 (Website). The advisory is available at securitytracker.com. This vulnerability is handled as CVE-2009-4445 since 12/29/2009. The attack may be launched remotely. The successful exploitation requires a simple authentication. Technical details are known, but there is no available exploit.
