Title: Microsoft Internet Explorer HTTP Request Encoding Vulnerability

Severity: MODERATE

Description:

Internet Explorer contains a vulnerability which could allow an attacker to construct a URL which would redirect the user to a third party website and send commands to that site which, to the third party site, would appear to have come from the user.

This vulnerability would most likely be exploited against a user who subscribed to some form of web-based service such as email or file hosting.

Successful exploitation of this vulnerability would require specific knowledge of the targetted user and be difficult to exploit on a widespread scale.
