Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly requires validation of information inputs like file types in the temp_file_upload function to prevent arbitrary file uploads.

SI-2 Flaw Remediation good match

prevent

Mandates timely identification, reporting, and correction of flaws such as the unrestricted file upload vulnerability in the plugin up to version 2.2.1.

SI-3 Malicious Code Protection partial match

preventdetect

Deploys malicious code protection at system entry points to detect and eradicate potentially executable files uploaded via the vulnerability.
