A server-side request forgery (SSRF) vulnerability has been identified in DataLinkDC Dinky versions through 1.2.5. The issue resides in the Flink Proxy Controller, specifically within the 'proxyUba' function of the 'FlinkProxyController.java' file. This vulnerability allows authenticated users to send arbitrary URLs that the server will request without proper validation. As a result, attackers can access internal network resources, cloud metadata services, and localhost services, potentially leading to credential theft and unauthorized access to sensitive data.
It is recommended to implement a URL whitelist to restrict proxy targets to trusted Flink cluster endpoints, add network-level controls to block access to cloud metadata services and internal IP ranges, strengthen authorization by restricting proxy access to specific user roles, and implement monitoring and alerting for proxy requests.
