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 Console WebUI to neutralize special characters that enable OS command injection (CWE-78).

AC-3 Access Enforcement good match
prevent

Enforces access-control policy on the WebUI, blocking unauthenticated remote attackers from reaching the vulnerable command-execution path.

AC-17 Remote Access partial match
prevent

Restricts and authorizes all remote access to the WF-500 WebUI, reducing the network attack surface that the unauthenticated injection exploits.
