Published Oct 15, 2026 CVSS 4.0 · 9.4 Critical EPSS < 1% KEV · Not listed
Description
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.
