Microsoft Windows Server 2003/XP IPv6 Stack TCP entropy

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 Server 2003/XP (Operating System). It has been rated as critical. Affected by this issue is an unknown part of the component IPv6 Stack TCP Handler. The manipulation with an unknown input leads to a entropy vulnerability. Using CWE to declare the problem leads to CWE-331. The product uses an algorithm or scheme that produces insufficient entropy, leaving patterns or clusters of values that are more likely to occur than others. Impacted is availability. CVE summarizes:

TCP, when using a large Window Size, makes it easier for remote attackers to guess sequence numbers and cause a denial of service (connection loss) to persistent TCP connections by repeatedly injecting a TCP RST packet, especially in protocols that use long-lived connections, such as BGP.

The bug was discovered 07/30/2003. The weakness was published 10/10/2006 by Paul with Microsoft as MS06-064 as confirmed bulletin (Technet). The advisory is shared for download at microsoft.com. This vulnerability is handled as CVE-2004-0230 since 03/17/2004. 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 MITRE ATT&CK project declares the attack technique as T1600.001.

The exploit is available at packetstormsecurity.org. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 209 days. During that time the estimated underground price was around $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 18023 (MS05-019: Vulnerabilities in TCP/IP Could Allow Remote Code Execution (893066)), 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 82054 (TCP Sequence Number Approximation Based Denial of Service).

Applying the patch MS06-064 is able to eliminate this problem. The bugfix is ready for download at windowsupdate.microsoft.com. A possible mitigation has been published before and not just after the disclosure of the vulnerability. Attack attempts may be identified with Snort ID 2523.

The vulnerability is also documented in the databases at X-Force (15886), Exploit-DB (276), Tenable (18023), SecurityFocus (BID 10183†) and OSVDB (4030†). Similar entries are available at VDB-1361, VDB-2599, VDB-2601 and VDB-9965. If you want to get best quality of vulnerability data, you may have to visit VulDB.
