Horizon Alert
Summary of the vulnerability and why it matters
The Windows Graphics Component is vulnerable due to an integer overflow weakness. This flaw allows an attacker to execute arbitrary code on affected systems, potentially leading to complete system compromise. The vulnerability requires local access but does not need user interaction, enabling an attacker with low privileges to elevate their privileges and execute code.
- Vulnerable: Windows Graphics Component
- Weakness: Integer overflow allows code execution
- Impact: System compromise, data theft, privilege escalation
Attack Path
How an attacker could exploit the issue
A local attacker can exploit a vulnerability in the Windows Graphics Component. This occurs when a specially crafted document or application is opened by a user with low privileges on an affected system. Successful exploitation allows the attacker to elevate their privileges, potentially leading to unauthorized access and control over the system. This could impact data integrity and confidentiality.
- Local attacker with low privileges.
- Triggered by opening a crafted document.
- Results in privilege escalation.
Live Threat
Current exploitation, exposure, and threat context
