Microsoft Windows 2000/XP Workstation Service stack-based overflow

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.

A vulnerability was found in Microsoft Windows 2000/XP (Operating System) and classified as critical. This issue affects an unknown code block of the component Workstation Service. The manipulation with an unknown input leads to a stack-based overflow vulnerability. Using CWE to declare the problem leads to CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Stack-based buffer overflow in a logging function for Windows Workstation Service (WKSSVC.DLL) allows remote attackers to execute arbitrary code via RPC calls that cause long entries to be written to a debug log file ("NetSetup.LOG"), as demonstrated using the NetAddAlternateComputerName API.

The bug was discovered 09/15/2003. The weakness was presented 11/11/2003 by Yuji Ukai (DiGiT) with eEye Digital Security as MS03-049 as confirmed bulletin (Technet). It is possible to read the advisory at microsoft.com. The identification of this vulnerability is CVE-2003-0812 since 09/18/2003. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details are unknown but a public exploit is available.

After immediately, there has been an exploit disclosed. The exploit is available at securiteam.com. It is declared as highly functional. The vulnerability was handled as a non-public zero-day exploit for at least 1363 days. During that time the estimated underground price was around $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 11921 (MS03-049: Buffer Overflow in the Workstation Service (828749)), 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.
