Noroxi assessment
Priority: Now (action score 85/100)
- CISA has confirmed exploitation in the wild (Jul 29, 2024). Remediation deadline for US federal agencies: Aug 19, 2024.
- A ready-made attack module is public (Metasploit, Nuclei); exploiting it takes no special expertise.
- Probability of exploitation in the next 30 days: 53.2% (FIRST EPSS); higher than 98.9% 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 CISA the attack is automatable: targets can be found by mass scanning.
- Fixed version: Acronis Acronis Cyber Infrastructure 5.0.1-61, 5.1.1-71, 5.2.1-69.
Patch today or shut off access. Upgrade to Acronis Acronis Cyber Infrastructure 5.0.1-61, 5.1.1-71, 5.2.1-69 or later.
