AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Local agent interface reachable only with an existing low-privileged account (AV:L, PR:L), no user interaction, and successful EoP yields full SYSTEM/root control giving high C/I/A.

Lifecycle Timeline
2DescriptionCVE.org
Dell Server Hardware Manager, versions prior to 3.2.2, contains an Improper Access Control vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Elevation of privileges.
AnalysisAI
Local privilege escalation in Dell Server Hardware Manager versions prior to 3.2.2 allows a low-privileged local user to gain higher privileges due to improper access control (CWE-284). The CVSS 7.8 (AV:L/AC:L/PR:L/UI:N) reflects high impact across confidentiality, integrity, and availability once exploited. No public exploit identified at time of analysis and the CVE is not in CISA KEV.
Technical ContextAI
Dell Server Hardware Manager (cpe:2.3:a:dell:server_hardware_manager) is Dell's agent software for monitoring and managing server hardware components on supported PowerEdge and related platforms. The root cause is classified as CWE-284 (Improper Access Control), meaning a security-relevant resource - likely a service endpoint, IPC channel, file/registry ACL, or privileged operation exposed by the management agent - does not adequately restrict which local principals may invoke it. Because the agent typically runs with elevated rights to perform hardware-level operations, weak access enforcement between a low-privileged caller and the privileged worker is the classic path to local elevation of privilege.
RemediationAI
Vendor-released patch: Dell Server Hardware Manager 3.2.2 - upgrade all installations to version 3.2.2 or later per Dell advisory DSA-2026-243 (https://www.dell.com/support/kbdoc/en-us/000478484/dsa-2026-243-security-update-for-dell-server-hardware-manager-vulnerability). Until the upgrade can be deployed, restrict interactive and remote-shell access to systems running the agent so that only trusted administrators have local accounts (this reduces the pool of principals who satisfy the PR:L precondition, at the cost of operational friction for support staff); audit local group membership and remove unnecessary standard users from hosts running Server Hardware Manager; and where feasible, stop or disable the Server Hardware Manager service on systems that do not actively require hardware monitoring (trade-off: loss of inventory, fault, and thermal telemetry from those hosts). No specific port-block or feature-disable workaround is published by Dell, so the upgrade is the only confirmed fix.
