F5 BIG-IP appliances 9.x before 9.4.8-HF5, 10.x before 10.2.4, 11.0.x before 11.0.0-HF2, and 11.1.x before 11.1.0-HF3, and Enterprise Manager before 2.1.0-HF2, 2.2.x before 2.2.0-HF1, and 2.3.x before 2.3.0-HF3, use a single SSH private key across different customers' installations and do not properly restrict access to this key, which makes it easier for remote attackers to perform SSH logins via the PubkeyAuthentication option.

  • Detect SSH authentication attempts using the known F5 BIG-IP hardcoded RSA public key fingerprint 71:3a:b0:18:e2:6c:41:18:4e:56:1e:fd:d2:49:97:66 on port 22.
  • Alert on SSH logins to F5 BIG-IP devices as 'root' using publickey authentication (PubkeyAuthentication), especially from unexpected source IPs.
  • Monitor for the presence or use of the known hardcoded RSA private key (MIICWgIBAAKBgQC8iELmyRPPHIeJ...) in SSH session negotiation or on disk.
  • Look for the Metasploit module 'exploits/linux/ssh/f5_bigip_known_privkey' being used; it targets port 22 with auth_methods set to 'publickey' and spawns /bin/sh.
  • ·The hardcoded SSH key pair is present on all vulnerable BIG-IP appliances across all customer installations; the private key is publicly known and identical on every affected device.
  • ·Only BIG-IP platforms WITHOUT SCCP are affected; patched versions are 9.4.8-HF5+, 10.2.4+, 11.0.0-HF2+, 11.1.0-HF3+, and Enterprise Manager 2.1.0-HF2+, 2.2.0-HF1+, 2.3.0-HF3+.
