CVE-2021-20544Network attack vector

Authenticated SSRF via arbitrary outbound requests

Published Jun 24, 2022 · Updated Sep 16, 2024

SSRF in IBM Jazz Team Server 6.0.6, 6.0.6.1, 7.0, 7.0.1, and 7.0.2 allows remote authenticated users to send arbitrary HTTP requests. The application accepts an attacker-controlled destination and issues server-side HTTP or HTTPS requests to arbitrary domains; IBM has not disclosed the endpoint or function. A valid account is required, and the resulting requests can enumerate network resources reachable from the server or interact with accessible services.
