Noroxi assessment
Priority: This week (action score 64/100)
- CISA has confirmed exploitation in the wild (Mar 18, 2025); it is known to be used in ransomware campaigns. Remediation deadline for US federal agencies: Apr 8, 2025.
- Probability of exploitation in the next 30 days: 7.2% (FIRST EPSS); higher than 94.3% 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.
Don’t wait for the next maintenance window. Until a fix is released, restrict access to the affected component and follow the vendor's advisory.
