Title: NT IIS ASP Alternate Data Streams Vulnerability
Severity: MODERATE
Description:
Microsoft IIS (Internet Information Services) and other NT webservers contain a vulnerability that allows remote attackers to obtain the of requested ASP (Active Server Pages) files.
ASP pages are executed on the server side and the results are sent to a user's browser. However, when an attacker appends the string, '::$DATA', when requesting a ASP page, IIS will respond by returning the contents of the ASP page to the attacker. This is due to IIS improperly handling requests for alternate data streams.
An attacker directly requesting a file with its complete data stream name, an attacker's Web browser is able to view the contents of the requested file. An attacker can use the information obtained to launch other attacks against a vulnerable system.
