Short explanation

CVE-2026-16438 is a critical incorrect privilege assignment vulnerability affecting Mitsubishi Electric GENESIS64, ICONICS Suite, Hyper Historian, AnalytiX, MobileHMI, and MC Works64. Installers unnecessarily grant default DCOM permissions, allowing attackers to launch and operate DCOM objects locally or remotely.

Why does it matter?

This vulnerability allows accounts with administrative access to launch DCOM objects that should normally require UAC elevation. Successful exploitation can lead to internal information disclosure, data tampering, destruction, or a denial-of-service condition.

What should be done?

  • Monitor vendor security advisories
  • Follow vendor recommendations as patch status remains unverified

Incorrect Privilege Assignment vulnerability in Mitsubishi Electric GENESIS64 versions 10.97.3 and prior, ICONICS Suite versions 10.97.3 and prior, Hyper Historian versions 10.97.3 and prior, AnalytiX versions 10.97.3 and prior, MobileHMI 10.97.3 and prior, MC Works64 all versions, Mitsubishi Electric Iconics Digital Solutions GENESIS64 versions 10.97.3 and prior, ICONICS Suite versions 10.97.3 and prior, Hyper Historian versions 10.97.3 and prior, AnalytiX versions 10.97.3 and prior, and MobileHMI 10.97.3 and prior allows an attacker who can log in using the same administrator account for the affected products to launch and operate DCOM objects locally or remotely. During installation, the installers of the affected products unnecessarily grant default DCOM permissions to the administrator account of the affected products. Users with that administrator accounts can locally or remotely launch and operate DCOM objects that should require UAC elevation. As a result, the attacker may disclose, tamper with, destroy, or delete internal information, or cause the affected system to enter a denial-of-service (DoS) condition.
