Technical details
The vulnerability is a Server-Side Request Forgery (CWE-918) in the ds-canvas pod component of DataStage on Cloud Pak for Data. An authenticated attacker with no project membership or role can fully control the scheme, host, port, and path of outbound HTTP fetch requests originating from a shared-infrastructure pod. The WSDL response body is reflected verbatim back to the caller. The ds-canvas pod runs on the OpenShift overlay network with access to co-tenant services, in-cluster CP4D APIs, and link-local addresses. Attack requires network reachability and authentication to the platform. An attacker can perform reconnaissance of internal infrastructure, access internal APIs, and exfiltrate sensitive data from co-tenant systems. This vulnerability has a scope change (crossing trust boundaries) and high confidentiality impact due to response reflection.
