Noroxi assessment

Priority: Monitor (action score 25/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.27% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: azl3 nodejs 24.17.0-1 on Azure Linux 3.0 24.18.1-1.

Low priority for now. Upgrade to azl3 nodejs 24.17.0-1 on Azure Linux 3.0 24.18.1-1 or later.
