Microsoft Windows up to XP Remote Desktop Service code injection

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 classified as very critical was found in Microsoft Windows 7/Server 2003/Server 2008/Vista/XP (Operating System). This vulnerability affects an unknown part of the component Remote Desktop Service. The manipulation with an unknown input leads to a code injection vulnerability. The CWE definition for the vulnerability is CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

The Remote Desktop Protocol (RDP) implementation in Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2, R2, and R2 SP1, and Windows 7 Gold and SP1 does not properly process packets in memory, which allows remote attackers to execute arbitrary code by sending crafted RDP packets triggering access to an object that (1) was not properly initialized or (2) is deleted, aka "Remote Desktop Protocol Vulnerability."

The weakness was presented 03/13/2012 by Luigi Auriemma as MS12-020 as confirmed article (Microsoft Technet) via ZDI (Zero Day Initiative). The advisory is available at technet.microsoft.com. The public release was coordinated in cooperation with the vendor. This vulnerability was named CVE-2012-0002 since 11/09/2011. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details are unknown but a public exploit is available. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 07/06/2025). This vulnerability is assigned to T1059 by the MITRE ATT&CK project. This vulnerability has a historic impact due to its background and reception.

A public exploit has been developed by Luigi Auriemma and been published 3 days after the advisory. It is possible to download the exploit at aluigi.org. It is declared as highly functional. The vulnerability was handled as a non-public zero-day exploit for at least 202 days. During that time the estimated underground price was around $100k and more. The vulnerability scanner Nessus provides a plugin with the ID 58332 (MS12-020: Vulnerabilities in Remote Desktop Could Allow Remote Code Execution (2671387)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Windows : Microsoft Bulletins and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 90783 (Microsoft Windows Remote Desktop Protocol Remote Code Execution Vulnerability (MS12-020)).

Applying the patch MS12-020 is able to eliminate this problem. The bugfix is ready for download at technet.microsoft.com.Proper firewalling of tcp/3389 (rdp) is able to address this issue. The best possible mitigation is suggested to be patching the affected component. A possible mitigation has been published immediately after the disclosure of the vulnerability. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 12138.

The vulnerability is also documented in the databases at X-Force (73543), Exploit-DB (18606), Tenable (58332), SecurityFocus (BID 52353†) and OSVDB (80000†).
