Microsoft Windows input validation

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 problematic, has been found in Microsoft Windows. This issue affects some unknown processing. The manipulation leads to input validation. This vulnerability is listed as CVE-2010-3944. The attack must be carried out locally. In addition, an exploit is available.

Detailsinfo

A vulnerability was found in Microsoft Windows (Operating System) (affected version unknown). It has been rated as critical. This issue affects an unknown functionality. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

win32k.sys in the kernel-mode drivers in Microsoft Windows Server 2008 R2 and Windows 7 does not properly validate user-mode input, which allows local users to gain privileges via a crafted application, aka "Win32k Memory Corruption Vulnerability."

The weakness was presented 12/16/2010 by Stefan LE BERRE with Sysdream (Website). It is possible to read the advisory at us-cert.gov. The identification of this vulnerability is CVE-2010-3944 since 10/14/2010. The exploitation is known to be easy. Attacking locally is a requirement. The successful exploitation needs a simple authentication. Technical details are unknown but a public exploit is available.

A public exploit has been developed by Stefan LE BERRE in ANSI C and been published 1 days after the advisory. The exploit is available at securityfocus.com. It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 51170 (MS10-098: Vulnerabilities in Windows Kernel-Mode Drivers Could Allow Elevation of Privilege (2436673)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Windows : Microsoft Bulletins. The commercial vulnerability scanner Qualys is able to test this issue with plugin 90664 (Microsoft Windows Kernel-Mode Drivers Elevation of Privilege Vulnerabilities (MS10-098)).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the databases at X-Force (63580), Exploit-DB (15758), Tenable (51170), SecurityFocus (BID 45298†) and SecurityTracker (ID 1024880†).
