CVE-2026-36933Public exploit

Physical code execution via forgeable factory-test signatures

Published Jun 15, 2026 · Updated Jun 15, 2026

Improper access control in Boyleep K11 y108 firmware 2.3.0.11291 allows physically proximate attackers to execute arbitrary code. At startup, /etc/init.d/rcS passes attacker-supplied auth.ini and factorytest.sh files from a microSD card to safe_exec.sh, while the bundled ukey utility can generate the signature that the verifier trusts. Exploitation requires inserting the crafted card and restarting the camera, after which the factory-test script runs with root privileges and can alter the device without disrupting video.
