Executive Summary

This is a Server-Side Request Forgery (SSRF) vulnerability in the feedmob fm-mcp-servers 0.0.3 component. It occurs in the downloadReport function of src/smadex-reporting/src/index.ts. The issue allows manipulation of the downloadUrl parameter to force the server to send HTTP requests to arbitrary internal or external targets, including localhost or private network services. The vulnerability exists because the downloadUrl is not properly validated as a URL or restricted to allowed destinations before being passed to the fetch() function.

Detection Guidance

Check for unusual outbound network requests from the feedmob fm-mcp-servers process, especially to localhost or private IP ranges. Monitor logs for the downloadReport function being called with suspicious downloadUrl parameters. Use network traffic analysis tools like tcpdump or Wireshark to inspect requests originating from the server.

Impact Analysis

An attacker could exploit this to access internal network services, read sensitive data from internal systems, or interact with services not intended to be exposed. Since the attack can be performed from a local environment and the exploit is publicly available, the risk is elevated. The vulnerability could lead to unauthorized data exfiltration or internal service probing if the server is running in a network with other services.

Compliance Impact

This SSRF vulnerability could lead to unauthorized access to sensitive data, violating GDPR's data protection principles or HIPAA's security requirements for protected health information. Organizations may face compliance violations if this vulnerability results in data breaches or unauthorized data exposure. The lack of proper network boundary validation increases the risk of non-compliance with data protection regulations.

Mitigation Strategies

Disable or restrict access to the downloadReport function in the fm-mcp-servers. Implement strict URL validation for the downloadUrl parameter, including allowlisting of permitted domains and blocking localhost or private IP addresses. Update to a patched version if available or apply network-level restrictions to prevent SSRF attacks.
