CVE-2023-50488Public exploit

Root code execution via predictable factory-test key

Published Feb 2, 2024 · Updated Jun 17, 2025

Code injection in Blurams Lumi Security Camera A31C firmware 23.0406.435.4120 allows physically proximate attackers to execute code as root. On reboot, the factory-test startup path accepts an auth.ini key derived solely from the public firmware version and runs factorytest.sh from an SD card as root. Physical access to insert the card and reboot the camera is required; successful exploitation grants full device control and prevents normal camera services from starting.
