Attack-Flow Graph

Executive Summary

This vulnerability is a server-side request forgery (SSRF) in the Model Context Protocol mcp-rdf-explorer 1.0.0. It exists in the explore_url function of src/mcp-rdf-explorer/server.py where manipulating the url argument allows an attacker to force the server to make unauthorized requests. The exploit is public and the vendor did not respond to disclosure attempts.

Detection Guidance

Detecting this vulnerability requires checking for server-side request forgery (SSRF) in the MCP Server component. Inspect network traffic for unusual outbound requests from the mcp-rdf-explorer server. Monitor logs for the explore_url function in src/mcp-rdf-explorer/server.py for unexpected URL manipulations.

Impact Analysis

An attacker could exploit this to send crafted requests from your server to internal or external systems, potentially accessing sensitive data, bypassing firewalls, or initiating further attacks. This could lead to data breaches, unauthorized access, or service disruption depending on the server's configuration and network.

Compliance Impact

This SSRF vulnerability could lead to unauthorized data access or exfiltration, violating GDPR's data protection principles or HIPAA's safeguards for protected health information. Non-compliance may result in legal penalties, fines, or reputational damage depending on the data involved.

Mitigation Strategies

Immediately update or patch the mcp-rdf-explorer component to a fixed version. If no patch is available, disable the explore_url function or restrict network access to the MCP Server. Implement input validation for URL parameters to prevent SSRF attacks.
