The tool that Dahua claims will alert users if Dahua's firmware is out-of-date does not work if the firmware is actually out-of-date, per a declaration that Dahua provided to IPVM after we reported on Dahua's newest critical vulnerabilities and the fact that their firmware checker did not work on out-of-date firmware we tested.
Inside this note, we share Dahua's explanation, our test findings, and why this increases risks for Dahua users already beset by vulnerability after vulnerability.
