CVE-2023-2131Network attack vector

Unauthenticated code execution via OS command injection

Published Apr 20, 2023 · Updated Jan 16, 2025

OS command injection in INEA remote terminal unit device code before 3.36 allows remote attackers to execute arbitrary code over the network. The published advisory does not identify the request field, endpoint, or command-building routine that fails to neutralize attacker-controlled input. No authentication or user interaction is required, and successful exploitation grants root-level control of the RTU.
