Mitsubishi E-Designer, Version 7.52 Build 344 contains two code sections which may be exploited to allow an attacker to overwrite arbitrary memory locations. This can result in arbitrary code execution, compromised data integrity, denial of service, and system crash.
Source: NIST NVD / MITRE CVE Database
The vulnerability exists in two code sections within Mitsubishi E-Designer, which can be remotely exploited over the network without authentication. An attacker can leverage this vulnerability to overwrite arbitrary memory locations, potentially leading to arbitrary code execution, data corruption, denial of service, and system instability. The lack of authentication and user interaction requirements makes this vulnerability particularly dangerous in an ICS environment where system availability and integrity are paramount.

Implement network segmentation and access controls to restrict communication to the affected E-Designer application. Monitor network traffic for suspicious activity and apply regular updates and patches as they become available.
No reliable network detection signature exists for this vulnerability class — apply the compensating controls above and the vendor patch. SAGE only publishes a network rule when a concrete on-the-wire signature can be grounded in the advisory.
This CVE violates CIP-007-R2 because it allows unauthorized access to the control system, which could lead to the compromise of critical cyber assets and the disruption of power delivery.
This CVE maps to SR 7.6 because it involves a vulnerability that can be exploited to execute arbitrary code, which directly impacts the security of the industrial control system and the integrity of its operations.
Virtual patch generated by CITED Relevance SAGE. Validate in isolated environment before production deployment. Compensating control only - does not replace vendor patch.
