Improper directory permissions in the installer for Intel(R) Management Engine Consumer Driver for Windows before versions 11.8.70, 11.11.70, 11.22.70, 12.0.45,13.0.10 and 14.0.10; Intel(R) TXE before versions 3.1.70 and 4.0.20 may allow an authenticated user to potentially enable escalation of privilege via local access.
AnalysisAI
Improper directory permissions in the installer for Intel(R) Management Engine Consumer Driver for Windows before versions 11.8.70, 11.11.70, 11.22.70, 12.0.45,13.0.10 and 14.0.10; Intel(R) TXE. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. No vendor patch available.
Technical ContextAI
This vulnerability is classified as Incorrect Default Permissions (CWE-276), which allows attackers to access resources due to overly permissive default settings. Improper directory permissions in the installer for Intel(R) Management Engine Consumer Driver for Windows before versions 11.8.70, 11.11.70, 11.22.70, 12.0.45,13.0.10 and 14.0.10; Intel(R) TXE before versions 3.1.70 and 4.0.20 may allow an authenticated user to potentially enable escalation of privilege via local access. Affected products include: Intel Trusted Execution Engine Firmware.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Set restrictive default permissions, follow principle of least privilege, review defaults during deployment.
