CVE-2021-20483Network attack vector

Sensitive-data access via authenticated server-side request forgery

Published Jun 16, 2021 · Updated Sep 16, 2024

Server-side request forgery in IBM Security Identity Manager 6.0.2 allows remote authenticated users to obtain sensitive data. IBM identifies the Password Synchronization Plug-in for Windows AD as the affected context but does not disclose the request handler, parameter, or destination-validation failure. Exploitation requires a crafted request to an authenticated interface and is bounded to sensitive-data access; no service interruption or code execution is reported.
