FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. Version 1.3.0 has an unauthenticated Remote Code Execution vulnerability when `secureEnabled` is set to `true`. The `POST /api/runscript` endpoint checks authorization against the stored script's permission by ID, but when `test: true` is set in the request, it compiles and executes attacker-supplied code instead of the stored script's code. An unauthenticated attacker who knows a valid script ID and name may execute arbitrary code via test mode if at least one server-side script exists and is accessible without restrictive permissions. Script IDs and names can be obtained through the unauthenticated information disclosure in `GET /api/project` (reported separately). The only prerequisite is that at least one server-side script exists in the project. Version 1.3.1 fixes the issue.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
