Published: 21 August 2025
Summary
CVE-2025-3128 is a critical-severity OS Command Injection (CWE-78) vulnerability in Mitsubishielectric (inferred from references). Its CVSS base score is 9.3 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 22.2th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2025-3128, published on 2025-08-21, is a critical vulnerability (CVSS 9.8, CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) classified under CWE-78 (OS Command Injection) affecting Mitsubishi Electric smartRTU. The flaw enables a remote unauthenticated attacker who has bypassed authentication to execute arbitrary OS commands on the product.
A remote unauthenticated attacker can exploit this vulnerability to disclose, tamper with, destroy, or delete information in the smartRTU, or cause a denial-of-service condition. The attack requires low complexity, no privileges, no user interaction, and operates over the network with unchanged scope.
