Secunia

Brett Moore has reported a vulnerability in Microsoft Internet Information Services, which can be exploited by malicious users to compromise a vulnerable system.

The vulnerability is caused due to a boundary error in asp.dll when handling ASP code. This can be exploited to cause a stack-based buffer overflow by placing ASP code that attempts to include a file with an overly long name (longer than 260 bytes).

Successful exploitation allows bypassing any security restrictions enforced by ASP or execution of API's with no ASP equivalent, but requires permissions to upload ASP code to a web folder.
