An attacker can exploit this by crafting a malicious chatflow that executes arbitrary code on the server through the Custom Tool functionality. The vulnerability exists due to insufficient input validation in the custom tool code execution path. + +**Attack Vector:** +An attacker can: +1. Access the Flowise API (often exposed without authentication) +2. Create a malicious chatflow with embedded code in the Custom Tool configuration +3. Trigger the chatflow to execute arbitrary commands on the server + +## Detection Method + +This detector: +1. Identifies Flowise instances by querying the `/api/v1/chatflows` endpoint +2. Creates a test chatflow with a payload that triggers a callback to the Tsunami callback server +3. Executes the chatflow to trigger the RCE +4. Verifies exploitation by checking if the callback was received +5. Cleans up by deleting the test chatflow + +## Testing + +Run the unit tests: + +```bash +python3 -m pytest flowise_rce_cve_2025_58434_test.py +``` + +Or with coverage: + +```bash +python3 -m pytest --cov=flowise_rce_cve_2025_58434 flowise_rce_cve_2025_58434_test.py +``` + +## Configuration + +No special configuration is required.

πŸ›‘οΈ Recommendations

+
+

Immediate Actions

+
    +
  • Upgrade LangChain: Update to version 0.3.18 or later immediately
    • +
  • Implement URL Allowlisting: Restrict document loader URLs to trusted domains
    • +
  • Network Segmentation: Isolate application servers from cloud metadata endpoints
    • +
+
+ +
+

Long-term Mitigations

+
    +
  • Implement WAF rules to block SSRF attempts
    • +
  • Use IMDSv2 for AWS EC2 instances
    • +
  • Enable VPC endpoints for cloud services
    • +
  • Implement request validation and sanitization
    • +
  • Deploy network monitoring for unusual outbound connections
    • +
  • Regular security audits of LangChain configurations
    • +
