CVE-2023-39256

Privilege escalation via writable installation folder

Published Dec 2, 2023 · Updated Aug 2, 2024

Improper access control in Dell Rugged Control Center before 4.7 allows local users to gain elevated privileges during installation or upgrade. The installation and upgrade workflow leaves a folder writable by standard users, allowing its contents to be modified during the privileged operation. Exploitation requires local low-privileged access and user interaction, and the resulting privilege escalation can compromise the system.
