Executive Summary

This vulnerability is a Server-Side Request Forgery (SSRF) in JeecgBoot version 3.9.2, specifically in the Airag anonymous chat feature. The /airag/chat/send endpoint allows unauthenticated users to upload remote HTTP/HTTPS file URLs via the files parameter. The backend downloads and processes these files using Apache Tika to extract text, which is then included in the model's context. The SSRF protection only blocks loopback and link-local addresses but fails to restrict private network ranges like 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16.

Detection Guidance

To detect this SSRF vulnerability in JeecgBoot, monitor network traffic for outbound requests from the /airag/chat/send endpoint to internal IP ranges (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16). Check Apache Tika logs for file downloads from external URLs. Use tools like curl to test the endpoint: curl -X POST http://<target>/airag/chat/send -F 'files=http://internal-server/secret'.

Impact Analysis

Attackers can force the server to access internal network resources by sending a crafted request with a malicious file URL. If the downloaded file is a supported document type (e.g., TXT, PDF, DOCX, XLSX), its contents may be leaked through the model's response. Exploitation requires no authentication and can lead to unauthorized access to sensitive data or internal systems.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, potentially violating GDPR (data protection) and HIPAA (healthcare data privacy) by exposing confidential information. Organizations using JeecgBoot may face compliance risks due to insufficient SSRF protections.

Mitigation Strategies

Immediately upgrade JeecgBoot to the latest version beyond 3.9.2. Temporarily disable the Airag anonymous chat feature if an update is unavailable. Restrict outbound network access from the server to private IP ranges. Implement stricter SSRF validation in SsrfFileTypeFilter to block all private network ranges, not just loopback and link-local addresses.
