Privilege escalation via insecure inherited permissions

Published May 13, 2025 · Updated May 14, 2025

Insecure inherited permissions in Intel Simics Package Manager before 1.12.0 allow local users with high privileges to escalate privileges. Intel has not disclosed which installed file or directory inherits unsafe permissions, which principal receives them, or how the permission is abused. Exploitation requires high privileges, local access, active user interaction, and an additional environmental condition; successful abuse compromises confidentiality, integrity, and availability.
