Microsoft CIS and RPC over HTTP Proxy components fail to properly handle responses

Vulnerability Note VU#698564

Original Release Date: 2004-04-14 | Last Revised: 2004-04-14

Overview

A vulnerability in a Microsoft HTTP Proxy component may lead to a denial of service.

Description

Microsoft's COM Internet Sevices (CIS) and Remote Procedure Call (RPC) over HTTP Proxy contain a vulnerability that could permit an attacker to cause a denial of service. When a forwarded request is passed over either of these components to the backend system, an attacker may be able to reply to the request with a specially crafted response. This could cause the vulnerable components to stop accepting future requests. This vulnerability affects the following systems:

    • Windows NT Server 4.0
    • Windows NT Server 4.0, Terminal Server Edition
    • Windows 2000
    • Windows Server 2003

Impact

A remote attacker may be able to stop the vulnerable component from accepting messages. This would lead to a denial of service.
