Microsoft Windows DNS Client Service Response Spoofing Vulnerability

Risk

Medium

Date Discovered

April 8, 2008

Description

Microsoft Windows operating systems are prone to a vulnerability that lets attackers spoof DNS clients. This issue occurs because the software fails to employ properly secure random numbers when creating DNS transaction IDs. Successfully exploiting this issue allows remote attackers to spoof DNS replies, allowing them to redirect network traffic and to launch man-in-the-middle attacks.
