Software contains embedded passwords or keys that cannot be changed by the administrator.
Mapping is CWE-to-CAPEC per MITRE CAPEC 3.9.
A critical vulnerability exists in Mitsubishi Electric Europe B.V. ME-RTU devices through 2.02 and INEA ME-RTU devices through 3.0, where hard-coded SSH keys allow unauthorized access and data disclosure. The keys are not regenerated during installation or firmware updates, making them publicly available and exploitable.
BSID: BS-2019-GLOBAL-202242-C • Model: Qwen/Qwen2.5-72B-Instruct-AWQ • Confidence: HIGH

An issue was discovered on Mitsubishi Electric Europe B.V. ME-RTU devices through 2.02 and INEA ME-RTU devices through 3.0. Hard-coded SSH keys allow an attacker to gain unauthorised access or disclose encrypted data on the RTU due to the keys not being regenerated on initial installation or with firmware updates. In other words, these devices use private-key values in /etc/ssh/ssh_host_rsa_key, /etc/ssh/ssh_host_ecdsa_key, and /etc/ssh/ssh_host_dsa_key files that are publicly available from the vendor web sites.
Source: NIST NVD / MITRE CVE Database
The vulnerability allows an attacker to leverage hard-coded SSH keys to gain unauthorized access to the RTU devices. This can lead to full control over the device, including the ability to execute arbitrary commands, modify configurations, and exfiltrate sensitive data. The attack can be performed remotely without any user interaction, making it highly dangerous in an OT environment.

Implement network segmentation to isolate the affected RTU devices from the rest of the network. Use a firewall to restrict SSH access to only trusted IP addresses. Regularly monitor network traffic for suspicious activity.
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 involves unauthorized access to a critical cyber asset, which could compromise the security and reliability of the power system.
This CVE maps to SR 7.6 because it involves the protection of communication channels against unauthorized access, which is essential for maintaining the integrity and confidentiality of data in industrial control systems.
Virtual patch generated by CITED Relevance SAGE. Validate in isolated environment before production deployment. Compensating control only - does not replace vendor patch.
