CVE-2024-34689Network attack vector

Internal endpoint enumeration via unrestricted callback URLs

Published Jul 9, 2024 · Updated Aug 2, 2024

SSRF in SAP Business Workflow WebFlow Services allows remote authenticated users to enumerate internal HTTP endpoints. WebFlow processes attacker-controlled callback URLs in crafted HTTP requests without restricting them to an allowlist, causing the server to contact internal destinations. A valid SAP account and network access to WebFlow Services are required, and successful requests disclose endpoint reachability without changing data or interrupting service.
