Title: Microsoft IIS SSI Buffer Overrun Privelege Elevation Vulnerability

Severity: MODERATE

Description:

Microsoft Internet Information Server versions 4.0 and 5.0 use Server Side Includes (SSI). Server-Side Includes allow an author to include dynamic elements such as the current time on a website.

A user who has write permission to the web content folders of an IIS server can upload a malformed SSI command that, when executed would cause a buffer overrun resulting in any code of the user's choosing running in Local System context.

By default unprivileged users do not have the permission to upload content to an IIS server.
