CVE-2022-1388: On F5 BIG-IP 16.1.x versions prior to 16.1.2.2, 15.1.x versions prior to 15.1.5.1, 14.1.x versions prior to 14.1.4.6, 13.1.x versions prior
Noroxi assessment
Priority: Now (action score 99/100)
- CISA has confirmed exploitation in the wild (May 10, 2022); it is known to be used in ransomware campaigns. Remediation deadline for US federal agencies: May 31, 2022.
- 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 CISA the attack is automatable: targets can be found by mass scanning.
- According to the record, no fixed version is available yet.
- Mentioned 6 times 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.
