Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly mitigates arbitrary file upload vulnerability by validating content and types of SVG or XML files uploaded to CmsWebFileAdminController to prevent code execution.

SI-9 Information Input Restrictions good match
prevent

Restricts file uploads to safe types and sources in the vulnerable controller, blocking crafted dangerous SVG or XML files.

AC-3 Access Enforcement good match
prevent

Enforces authentication and authorization requirements for access to the unauthenticated CmsWebFileAdminController upload endpoint.
