MediumCVSS 5.5 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 22/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.10% (FIRST EPSS).
Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
Fixed version: Dell OpenManage Server Administrator Managed Node (Patch) for Windows 11.1.0.3; Dell OpenManage Server Administrator Managed Node for RHEL 8.10 11.1.0.3; Dell OpenManage Server Administrator Managed Node for RHEL 9.4 11.1.0.3.

Low priority for now. Upgrade to Dell OpenManage Server Administrator Managed Node (Patch) for Windows 11.1.0.3; Dell OpenManage Server Administrator Managed Node for RHEL 8.10 11.1.0.3; Dell OpenManage Server Administrator Managed Node for RHEL 9.4 11.1.0.3 or later.
