|---|
| 説明 | module for managing device data sinks (destinations for IoT device message forwarding). A stored SSRF vulnerability exists in the platform’s IoT data sink configuration mechanism:
Authenticated administrators can create/modify HTTP/TCP/WebSocket/MQTT data sink configurations with arbitrary malicious URLs/addresses. These unvalidated connection addresses are persistently stored in the MySQL database. When an IoT device sends a message, the platform automatically triggers the data sink and uses RestTemplate (for HTTP) and native socket clients (for TCP/WebSocket/MQTT) to initiate outbound requests without any URL validation, internal IP filtering, protocol restrictions, or cloud metadata protection.
This flaw allows privileged attackers to force the yudao-cloud server to send unauthorized requests to internal network services, cloud instance metadata APIs, localhost services, or arbitrary external targets—fully bypassing network perimeter security controls. |
