Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly requires validation of all inputs to the WebUI to reject or neutralize special characters used for OS command injection (CWE-78).

AC-3 Access Enforcement good match
prevent

Enforces authentication and authorization on the Console WebUI before any commands can be processed, blocking the unauthenticated remote execution path.

AC-6 Least Privilege partial match
prevent

Restricts the privileges of the web-server process so that even a successful command injection yields minimal OS-level impact.
