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, which was classified as very critical, has been found in Microsoft Windows 2000/XP (Operating System). Affected by this issue is an unknown part 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. CVE summarizes:

Stack-based buffer overflow in the NetpManageIPCConnect function in the Workstation service (wkssvc.dll) in Microsoft Windows 2000 SP4 and XP SP2 allows remote attackers to execute arbitrary code via NetrJoinDomain2 RPC messages with a long hostname.

The bug was discovered 11/14/2006. The weakness was shared 11/14/2006 by JeongWook Matt Oh with eEye as MS06-070 (Website). The advisory is shared for download at research.eeye.com. This vulnerability is handled as CVE-2006-4691 since 09/11/2006. The attack may be launched remotely. No form of authentication is required for exploitation. Technical details are unknown but a public exploit is available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 07/10/2019).

A public exploit has been developed by Winny Thomas and been published 4 days after the advisory. The exploit is available at exploit-db.com. It is declared as highly functional. The vulnerability was handled as a non-public zero-day exploit for at least 2462 days. During that time the estimated underground price was around $100k and more. The vulnerability scanner Nessus provides a plugin with the ID 23646 (MS06-070: Vulnerability in Workstation Service Could Allow Remote Code Execution (924270)), 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.

Applying the patch MS06-070 is able to eliminate this problem. The bugfix is ready for download at microsoft.com.
