What happened

A weak password recovery mechanism lets a local, authenticated administrator unlock the product by tampering with the management file that stores the challenge response; the file is only protected by Windows permissions. CVE-2026-16437 is listed as an authentication bypass, with the advisory affecting GENESIS, GENESIS64, ICONICS Suite, Hyper Historian, AnalytiX, MobileHMI, IoTWorX, MC Works64, GENESIS32 and BizViz.

Why it is dangerous: Successful exploitation could allow disclosure, tampering, destruction or deletion of information, and a denial-of-service condition. The software is used in critical manufacturing environments worldwide.
