allows an attacker who successfully exploited this vulnerability to take
complete control of the affected system, the following exploit code can be
used to test your system for the mentioned vulnerability.
DETAILS
Vulnerable Systems:
* Microsoft Windows 2000 Service Pack 4
* Microsoft Windows XP Service Pack 1 and Microsoft Windows XP Service
Pack 2
* Microsoft Windows XP Professional x64 Edition
* Microsoft Windows Server 2003 and Microsoft Windows Server 2003 Service
Pack 1
* Microsoft Windows Server 2003 for Itanium-based Systems and Microsoft
Windows Server 2003 with SP1 for Itanium-based Systems
* Microsoft Windows Server 2003 x64 Edition
Immune Systems:
* Microsoft Windows 98, Microsoft Windows 98 Second Edition (SE), and
Microsoft Windows Millennium Edition (ME)
Exploit:
/* HOD-ms05039-pnp-expl.c: 2005-08-10: PUBLIC v.0.2

*
* ---------------------------------------------------------------------
* Description:
* A remote code execution and local elevation of privilege
* vulnerability exists in Plug and Play that could allow an
* attacker who successfully exploited this vulnerability to take
* complete control of the affected system.
*
* This is a remote code execution and local privilege elevation
* vulnerability. On Windows 2000, an anonymous attacker could
* remotely try to exploit this vulnerability.
*
* On Windows XP Service Pack 1, only an authenticated user could
* remotely try to exploit this vulnerability.
* On Window XP Service Pack 2 and Windows Server 2003, only an
* administrator can remotely access the affected component.
* Therefore, on Windows XP Service Pack 2 and Windows Server 2003,
* this is strictly a local privilege elevation vulnerability.
* An anonymous user cannot remotely attempt to exploit this
* vulnerability on Windows XP Service Pack 2 and Windows
* Server 2003.
