Noroxi assessment

Priority: Monitor (action score 26/100)

  • A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 60.3% (FIRST EPSS); higher than 99.1% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No special conditions are required; it is repeatable.
  • Fixed version: SPA-Cart eCommerce CMS 1.9.1.4.
  • Severity is disputed: the assigning authority (CNA) scores it 5.1, NVD 2.0.

Low priority for now. Upgrade to SPA-Cart eCommerce CMS 1.9.1.4 or later.
