AI-suggested
- Upgrade affected systems from Windows 10 Version 1507 to a supported and fully patched Windows version, such as Windows 10 LTSC or Windows 11, to eliminate exposure to this vulnerability.
- Implement strict access controls and monitoring to limit local user privileges and detect unauthorized access attempts, reducing the risk of local exploitation.
- Employ endpoint detection and response (EDR) solutions capable of identifying suspicious activities related to the User-Mode Driver Framework Host.
- Conduct regular audits of legacy systems to identify and prioritize remediation of outdated operating systems.
- If upgrading is not immediately feasible, apply any available Microsoft security advisories or workarounds that may mitigate information disclosure risks.
- Educate IT staff and users about the risks of running unsupported Windows versions and the importance of timely patching and system upgrades.
- Isolate legacy systems from critical network segments to reduce the impact of potential local exploits.
Description
Exposure of sensitive information to an unauthorized actor in Windows User-Mode Driver Framework Host allows an authorized attacker to disclose information locally.
