Noroxi assessment

Priority: Now (action score 96/100)

  • CISA has confirmed exploitation in the wild (Jan 10, 2024); it is known to be used in ransomware campaigns. Remediation deadline for US federal agencies: Jan 22, 2024.
  • A ready-made attack module is public (Metasploit, Nuclei); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 99.9% (FIRST EPSS); higher than 99.9% of all records.
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

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

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Jan 10, 2024. That signals real attacks, not theory.

Remediation deadline for US federal agencies: Jan 22, 2024.

Known to be used in ransomware campaigns.
