Summary

Windows USB Video Class System Driver Elevation of Privilege Vulnerability. This is an out-of-bounds read vulnerability affecting the Windows USB Video Class System Driver. The vulnerability requires physical access to exploit, has low attack complexity, and does not require privileges or user interaction.

Impact

If exploited, this vulnerability could allow an attacker with physical access to the system to elevate their privileges and potentially gain full control of the affected system. The impact on confidentiality, integrity, and availability is high, meaning an attacker could potentially read, modify, or delete sensitive data, or disrupt system operations. Given the physical access requirement, this vulnerability is most likely to be exploited in scenarios where an attacker has direct access to the device, such as stolen or unattended systems.

Exploitation

There is no evidence that a public proof-of-concept exists. There is no evidence of proof of exploitation at the moment.

Patch

A patch is available for this vulnerability. Microsoft released the patch on November 12, 2024. Security teams should prioritize applying this patch to affected systems, especially those that are at higher risk of physical access by unauthorized individuals.

Mitigation

1. Apply the security update provided by Microsoft as soon as possible. 2. Implement strong physical security measures to prevent unauthorized access to systems, particularly in public or shared spaces. 3. Use full-disk encryption on all systems to protect data in case of device theft. 4. Regularly update and patch all Windows systems to protect against this and other vulnerabilities. 5. Monitor systems for any suspicious activities, especially those related to privilege escalation or unauthorized access via USB devices. 6. Consider disabling or restricting USB ports on high-risk systems where video input is not required. 7. Implement the principle of least privilege across your environment to minimize the impact of potential exploits.
