Jooan JA-A12 Unauthenticated Root RCE via SetDiagMode Hard-Coded Credentials

Assigner: VulnCheck
Reserved: 15.10.2026 Published: 15.10.2026 Updated: 15.10.2026

Jooan JA-A12 IP cameras with firmware 009_20171107 and 05.02.31.105 contain a remote code execution vulnerability that allows unauthenticated attackers to run root commands via hard-coded credentials. Attackers send singleCMD=SetDiagMode to /goform/SingleHandlebyCommand with an attacker-chosen authserverip and authcode, making the jooandiag daemon execute their commands through /bin/sh, giving full device control.
