Vulnerability details

A security flaw was identified in one of the Service Center API endpoints. It allows any unauthenticated user with network access to Service Center to use the internal undocumented PingAddress API endpoint to instruct the Platform to perform HTTP GET requests to arbitrary addresses. By exploiting this flaw an attacker can use Service Center as a proxy to perform HTTP requests to an arbitrary address, while masking the source IP address. In extreme cases this flaw can crash the application server, causing the Platform to be unavailable.
