CVE-2020-25564Public exploitNetwork attack vector

Client administrator creation via unchecked automation task

Published Aug 11, 2021 · Updated Aug 4, 2024

Privilege escalation in SapphireIMS 5.0 allows remote authenticated users to create local administrator accounts on managed clients. The RemoteMgmtTaskSave Automation Tasks endpoint accepts direct low-privilege requests to schedule the User Account Creation task without enforcing the caller's authorization. Any non-privileged SapphireIMS account can therefore create a privileged client account and use it for administrative control.
