Remote Code Execution in WordPress File Manager Plugin (CVE‑2020‑25213) Threatens Unauthenticated Sites
What It Is — The WordPress File Manager plugin contains an unauthenticated remote‑code‑execution flaw that allows an attacker to upload and run arbitrary PHP files on a vulnerable site.
Exploitability — Public proof‑of‑concept exists; CVSS v3.1 base score 8.8 (High). No authentication is required.
Affected Products — WordPress installations that have the “File Manager” plugin installed (versions ≤ 7.0).
Why It Matters for Trust & Control Assurance
- Highlights the importance of continuous secure configuration and patch management—a control objective that satisfies many frameworks (e.g., NIST CSF Protect, ISO 27001 Asset Management).
- Absence of evidence that vulnerable third‑party components are removed weakens audit trails and can erode buyer confidence.
- Ongoing monitoring of plugin versions provides defensible proof of due‑diligence for regulators and enterprise customers.
Recommended Actions
- Inventory all WordPress sites and flag any that run the File Manager plugin.
- Upgrade to the patched release or remove the plugin entirely.
- Deploy automated scanning for vulnerable plugins and capture remediation evidence in your control repository.
- Document the remediation steps to satisfy audit requirements.
