CVE-2021-29738Network attack vector

Network enumeration via authenticated server-side request forgery

Published Nov 2, 2021 · Updated Sep 16, 2024

Server-side request forgery in IBM InfoSphere Data Flow Designer 11.7 allows remote authenticated users to send unauthorized requests. IBM has not published the affected endpoint or the request-validation failure that permits attacker-controlled destinations. Access to the authenticated Flow Designer interface is required, and exploitation exposes server-reachable services to network enumeration and follow-on requests.
