Noroxi assessment
Priority: Now (action score 96/100)
- CISA has confirmed exploitation in the wild (Jan 8, 2025); it is known to be used in ransomware campaigns. Remediation deadline for US federal agencies: Jan 15, 2025.
- A ready-made attack module is public (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. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
- 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.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
