CVE-2023-46747: BIG-IP Configuration utility unauthenticated remote code execution vulnerability

Noroxi assessment

Priority: Now (action score 98/100)

  • CISA has confirmed exploitation in the wild (Oct 31, 2023); it is known to be used in ransomware campaigns. Remediation deadline for US federal agencies: Nov 21, 2023.
  • A ready-made attack module is public (Metasploit, Nuclei); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 96.7% (FIRST EPSS); higher than 99.8% 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: F5 BIG-IP Hotfix-BIGIP-13.1.5.1.0.20.2-ENG.iso, Hotfix-BIGIP-14.1.5.6.0.10.6-ENG.iso, Hotfix-BIGIP-15.1.10.2.0.44.2-ENG.iso.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Patch today or shut off access. Upgrade to F5 BIG-IP Hotfix-BIGIP-13.1.5.1.0.20.2-ENG.iso, Hotfix-BIGIP-14.1.5.6.0.10.6-ENG.iso, Hotfix-BIGIP-15.1.10.2.0.44.2-ENG.iso or later.

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

Undisclosed requests may bypass configuration utility authentication, allowing an attacker with network access to the BIG-IP system through the management port and/or self IP addresses to execute arbitrary system commands.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated
