Assessment

CVE-2023-46747 can bypass BIG-IP Configuration Utility authentication and execute arbitrary system commands. The attacker needs network access through the management port or self IP addresses. ENISA lists the vulnerability as known exploited, and CISA KEV records known ransomware use.

Why it matters

  • Management ports and self IP addresses can expose administrative functions to reachable networks.
  • Successful command execution could allow an attacker to control functions on the affected BIG-IP system.

Evidence

1 record references and 1 source references passed trusted post-response validation. The current deterministic record contains 1 independent evidence group.

Uncertainties

The supplied Fortinet incident reporting does not concern F5 BIG-IP and provides no campaign evidence for this CVE.

First-party sensor telemetry is active; no disclosure-eligible deterministic observation is currently public for this CVE. This does not mean no activity was observed.

Next watchpoint

If you use affected F5 BIG-IP versions, apply F5's remediation for CVE-2023-46747.
