CVE-2021-39051Network attack vector

Internal service access via unvalidated registration fields

Published Mar 14, 2022 · Updated Sep 16, 2024

SSRF in IBM Storage Defender Copy Data Management 2.2.0.0 through 2.2.14.3 allows remote attackers to reach internal services. The application server registration function accepts attacker-controlled host and port fields from the portal UI and issues server-side requests without adequate validation. The unauthenticated form is network-reachable; successful requests use the appliance's trusted position to enumerate and attack reachable services.
