Microsoft Windows TCP/IP Stack resource management

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 (Operating System) (the affected version unknown). It has been classified as critical. Affected is an unknown part of the component TCP/IP Stack. The manipulation with an unknown input leads to a resource management vulnerability. CWE is classifying the issue as CWE-399. This is going to have an impact on availability. CVE summarizes:

Tcpip.sys in the TCP/IP stack in Microsoft Windows 7 Gold and SP1 and Windows Server 2008 R2 and R2 SP1 does not properly implement URL-based QoS, which allows remote attackers to cause a denial of service (reboot) via a crafted URL to a web server, aka "TCP/IP QOS Denial of Service Vulnerability."

The weakness was released 08/10/2011 by Byoungyoung Lee with Microsoft (Website). The advisory is shared for download at us-cert.gov. This vulnerability is traded as CVE-2011-1965. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details are unknown but a public exploit is available.

A public exploit has been developed by Byoungyoung Lee in Python and been published 3 months after the advisory. The exploit is shared for download at securityfocus.com. It is declared as proof-of-concept. As 0-day the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 56044 (MS11-064: Vulnerabilities in TCP/IP Stack Could Allow Denial of Service (2563894) (uncredentialed check)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Windows. The commercial vulnerability scanner Qualys is able to test this issue with plugin 90731 (Microsoft Windows TCP/IP Denial of Service Vulnerability (MS11-064)).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 11485.
