Executive Summary

This is a Server-Side Request Forgery (SSRF) vulnerability in FormTools version 3.1.1 or earlier. It exists in the smart_fill function of the AJAX Endpoint (global/code/actions.php). The flaw allows authenticated users to manipulate the url parameter to make the server send requests to arbitrary internal or external URLs without proper validation. The server then echoes the response back to the attacker.

Detection Guidance

To detect this SSRF vulnerability in FormTools 3.1.1, monitor network traffic for outbound requests from the server to unexpected internal or external URLs. Check logs for requests to the /global/code/actions.php endpoint with url or scrape_method parameters containing suspicious values like internal IPs, localhost, or file:// schemes. Use tools like tcpdump or Wireshark to capture outgoing connections from the server.

Impact Analysis

An attacker could exploit this to access internal services, read sensitive files (like /etc/passwd), or retrieve cloud metadata such as IAM credentials. This could lead to lateral movement within a network or full server compromise, especially if combined with other vulnerabilities like arbitrary file uploads.

Compliance Impact

This SSRF vulnerability could lead to unauthorized access to sensitive data, violating confidentiality requirements in GDPR and HIPAA. Exposure of personal or health data due to server compromise may result in compliance breaches, legal penalties, and reputational damage.

Mitigation Strategies
  • Upgrade to a patched version of FormTools if available. If not, apply URL validation to the smart_fill endpoint to restrict allowed schemes (e.g., only http/https) and block private/reserved IP ranges.
  • Restrict access to the vulnerable endpoint to administrators only and implement CSRF token validation for requests.
  • Disable redirects and reject unsafe protocols like file:// or gopher:// in the URL parameters.
