Noroxi assessment
Priority: Now (action score 99/100)
- CISA has confirmed exploitation in the wild (Apr 4, 2025); it is known to be used in ransomware campaigns. Remediation deadline for US federal agencies: Apr 11, 2025.
- 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. No account or password is 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.
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
Primary sources: NVD · CVE.org · CISA KEV · FIRST EPSS
