CVE-2025-8473

Physical root code execution via unvalidated system call

Published Aug 1, 2025 · Updated Aug 1, 2025

Command injection in Alpine iLX-507 firmware 6.0.000 allows physically proximate attackers to execute arbitrary code as root. The UPDM_wstpCBCUpdStart function passes user-supplied data to a system call without proper validation, allowing command injection. Exploitation requires physical presence and user interaction with the receiver; successful execution grants root-level control over the device.
