MS08-006 - Important - Vulnerability in Internet Information Services Could
Allow Remote Code Execution (942830)
Published: February 12, 2008
Version: 1.0
This important update resolves a privately reported vulnerability in
Internet Information Services (IIS). A remote code execution
vulnerability exists in the way that IIS handles input to ASP Web pages.
An attacker who successfully exploited this vulnerability could then
perform actions on the IIS server with the same rights as the Worker
Process Identity (WPI). The WPI is configured with Network Service
account privileges by default. IIS servers with ASP pages whose
application pools are configured with a WPI that uses an account with
administrative privileges could be more seriously impacted than IIS
servers whose application pool is configured with the default WPI
settings.

o Windows XP Professional Service Pack 2 - Microsoft Internet
Information Services 5.1
o Windows XP Professional x64 Edition and Windows XP Professional x64
Edition Service Pack 2 - Microsoft Internet Information Services 6.0
