Microsoft Windows 2000/XP RPCSS race condition

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in Microsoft Windows 2000/XP (Operating System). It has been declared as very critical. Affected by this vulnerability is some unknown functionality of the component RPCSS. The manipulation with an unknown input leads to a race condition vulnerability. The CWE definition for the vulnerability is CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

A multi-threaded race condition in the Windows RPC DCOM functionality with the MS03-039 patch installed allows remote attackers to cause a denial of service (crash or reboot) by causing two threads to process the same RPC request, which causes one thread to use memory after it has been freed, a different vulnerability than CVE-2003-0352 (Blaster/Nachi), CVE-2003-0715, and CVE-2003-0528, and as demonstrated by certain exploits against those vulnerabilities.

The bug was discovered 10/14/2003. The weakness was released 10/10/2003 by eEye Digital Security (ZARAZA and ISS) with eEye Digital Security as MS04-012 (Website). It is possible to read the advisory at xforce.iss.net. This vulnerability is known as CVE-2003-0813 since 09/18/2003. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details are unknown but a public exploit is available. The pricing for an exploit might be around USD $0-$5k at the moment (estimation calculated on 12/31/2024).

A public exploit has been developed in ANSI C. It is possible to download the exploit at securityfocus.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1331 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 21655 (MS04-012: Cumulative Update for Microsoft RPC/DCOM (828741) (uncredentialed check)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Windows and running in the context r. The commercial vulnerability scanner Qualys is able to test this issue with plugin 68528 (Multiple Microsoft Windows RPC/DCOM Vulnerabilities (MS04-012)).

Applying a patch is able to eliminate this problem. The bugfix is ready for download at windowsupdate.microsoft.com.Proper firewalling of is able to address this issue. The best possible mitigation is suggested to be applying a restrictive firewalling. Attack attempts may be identified with Snort ID 2496. In this case the pattern |05| is used for detection.
