Windows Plug and Play Remote Compromise

Summary:

X-force has discovered a vulnerability in the Windows Plug and Play service. This vulnerability is remotely exploitable in the default configuration of Windows 2000, and is present in all modern Windows operating systems. There is a high probability that this vulnerability will be exploited in an automated fashion as part of a worm on Windows 2000.

ISS Protection Strategy:

ISS has provided preemptive protection for this vulnerability. We recommend that all customers apply applicable ISS product updates if they have not already done so.

Business Impact:

Successful exploitation of this vulnerability could be leveraged to gain complete control over target systems, and might lead to malware installation, exposure of confidential information, or further network compromise. Due to the widespread use of the affected operating systems and the critical nature of component affected, it is likely that servers and desktops used for a wide variety of purposes are vulnerable to this issue.

Affected Products:

Windows 2000 up to and including SP4 with Security Rollup (Anonymous) Windows XP up to and including SP2 (Authenticated Users Only) Windows Server 2003 up to and including SP1 (Authenticated Users Only)

Description:

The Plug and Play service is a Windows DCE-RPC service that is designed to handle device installation, configuration, and notification of new devices. It starts automatically on modern versions of the Windows operating system, and runs in default configurations. On Windows 2000, this service is reachable via named pipes and a NULL session. It is not possible to disable this service without adversely affecting system operation.

This Plug and Play service contains a remotely exploitable stack-based overflow. It has been proven to be trivially exploitable, and X-Force is concerned that the overflow could be exploited automatically as part of a network-based worm used to attack Windows 2000-based systems.

The named-pipe needed to reach this service requires authentication on Windows XP and Windows Server 2003. On Windows XP SP2 and Windows Server 2003 those named-pipe are only available remotely to administrators. However, additional named pipe aliases are present on Windows 2000 which expose this service to an attacker with NULL session access. No authentication or user-interaction is required to exploit this vulnerability on Windows 2000.

At the time of publication, no exploits are available to the public at large. However, X-Force expects that exploits for this vulnerability will appear in the very near future.
