CVE-2021-21530Network attack vector

Privilege escalation via restricted-environment escape

Published Apr 30, 2021 · Updated Sep 16, 2024

Security bypass in Dell OpenManage Enterprise-Modular before 1.30.00 allows remote authenticated users to escape its restricted environment. Dell has not disclosed the affected component or the operation that mishandles untrusted input; the record only maps the flaw to OS command injection. Low-privilege access is required, after which the escape exposes sensitive system information and elevates privileges.
