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.

Executive Summary

This vulnerability involves incorrect privilege assignment in Mitsubishi Electric and ICONICS software products. During installation, default DCOM permissions are granted to administrator accounts, allowing users with those accounts to locally or remotely launch and operate DCOM objects without proper User Account Control (UAC) elevation. This can lead to unauthorized access and control of the affected systems.

Impact Analysis

An attacker exploiting this vulnerability could disclose, tamper with, destroy, or delete internal information. They may also cause the affected system to enter a denial-of-service (DoS) condition, disrupting normal operations.

Mitigation Strategies

Review and restrict DCOM permissions for administrator accounts in affected Mitsubishi Electric and ICONICS products. Remove unnecessary default DCOM permissions granted during installation. Apply the latest patches from Mitsubishi Electric for versions 10.97.3 and prior.
