Dell OpenManage Enterprise: local low-privileged user escalates privileges on the console appliance
Impact
A user with local access to the OpenManage Enterprise appliance can escalate privileges. Full privilege on the console means access to the stored iDRAC/BMC credentials and to the firmware and power-control workflows for every managed server. The practical exposure depends on who already has a local shell or local session on the appliance, which is usually a small set of infrastructure staff - this is a post-access escalation, not an entry point. Dell's record does not say which component mismanages privileges.
Who can reach it
Local access to the OME appliance with a low-privileged account. Authentication required; no remote path per Dell's vector.
What to do
Upgrade to OpenManage Enterprise 4.8.0 (DSA-2026-467). Appliance update and console restart; managed nodes are unaffected. Meanwhile restrict and audit local/shell access to the appliance.
