CVE-2026-9645Network attack vector

Authenticated root command execution via exposed scripting methods

Published May 28, 2026 · Updated May 28, 2026

OS command injection in ScadaBR 1.2.0 allows remote authenticated users to execute arbitrary JavaScript and commands as root. Tenable identifies exposed server-side scripting methods, but neither the advisory nor the CNA record names the methods or explains how untrusted script content reaches an operating-system command sink. Any authenticated account can reach the behavior over the network without user interaction, enabling complete control of the host and its SCADA functions.
