Microsoft MSN Messenger fails to properly validate file requests

Vulnerability Note VU#688094

Original Release Date: 2004-03-10 | Last Revised: 2004-03-15

Overview

Microsoft MSN Messenger fails to properly validate file requests which could allow an attacker to view the contents of files on the victim's system.

Description

Microsoft MSN Messenger is an instant messaging application that allows users to collaborate with friends using text messages, voice and video communication, or by sending files. There is a vulnerability in the way MSN Messenger handles incoming file requests from other users. By sending a specially crafted file request, a remote, unauthenticated attacker could view the contents of files on the victim's system with the privileges of the vulnerable process. This would require that the attacker had knowledge of the location of the file on the victim's system.

Impact

A remote, unauthenticated user could view the contents of files on the victim's system with privileges of the vulnerable process.
