Noroxi assessment

Priority: Monitor (action score 24/100)

  • 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: 0.88% (FIRST EPSS); higher than 59.7% of all records.
  • Someone on the same network segment can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Azure Arc Cluster microsoft.azstackhci.operator Extension 5.0.5; Azure Arc Cluster microsoft.azure.hybridnetwork Extension 1.0.2620-162; Azure Arc Cluster microsoft.azurekeyvaultsecretsprovider Extension 1.5.2.

Low priority for now. Upgrade to Azure Arc Cluster microsoft.azstackhci.operator Extension 5.0.5; Azure Arc Cluster microsoft.azure.hybridnetwork Extension 1.0.2620-162; Azure Arc Cluster microsoft.azurekeyvaultsecretsprovider Extension 1.5.2 or later.
