Description

ScadaLTS 2.7.8.1 exposes a server-side method that lacks authorization checks, allowing any authenticated user (including one holding only low-privilege, read-only permissions) to execute arbitrary operating system commands on the host. Successful exploitation results in code execution in the context of the ScadaLTS server process (root), leading to full compromise of the underlying system.
