Noroxi assessment

Priority: Now (action score 81/100)

  • CISA has confirmed exploitation in the wild (Aug 5, 2025). Remediation deadline for US federal agencies: Aug 26, 2025.
  • Probability of exploitation in the next 30 days: 54% (FIRST EPSS); higher than 99% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.

Patch today or shut off access. Until a fix is released, restrict access to the affected component and follow the vendor's advisory.
