A server-side request forgery (SSRF) vulnerability exists in multiple WSO2 products due to improper input validation in SOAP admin services. This flaw allows unauthenticated attackers to manipulate server-side requests, enabling access to internal and external resources available through the network or filesystem.
Exploitation of this vulnerability could lead to unauthorized access to sensitive data and systems, including resources within private networks, as long as they are reachable by the affected product.
The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
