Noroxi assessment

Priority: Monitor (action score 29/100)

  • 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: 0.24% (FIRST EPSS).
  • Someone with local access to the system can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: Azure Linux 3.0 ARM 1.14.4.3-1; Azure Linux 3.0 x64 1.14.4.3-1; CBL Mariner 2.0 ARM 1.14.4-1.

Low priority for now. Upgrade to Azure Linux 3.0 ARM 1.14.4.3-1; Azure Linux 3.0 x64 1.14.4.3-1; CBL Mariner 2.0 ARM 1.14.4-1 or later.
