Microsoft Windows Kernel code injection

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, was found in Microsoft Windows (Operating System) (version unknown). This affects an unknown function of the component Kernel. The manipulation with an unknown input leads to a code injection vulnerability. CWE is classifying the issue as CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. This is going to have an impact on confidentiality, and integrity. The summary by CVE is:

Unspecified vulnerability in the kernel in Microsoft Windows 2000 SP4, XP SP2, Server 2003 SP1 and SP2, through Vista SP1, and Server 2008 allows local users to execute arbitrary code via unknown vectors related to improper input validation. NOTE: it was later reported that one affected function is NtUserFnOUTSTRING in win32k.sys.

The bug was discovered 04/08/2008. The weakness was published 04/08/2008 by Thomas Garnier (kyREcon) with Microsoft as MS08-025 as confirmed bulletin (Technet).
