Description

F5 ships a public/private key pair on BIG-IP appliances that allows passwordless authentication to any other BIG-IP box. Since the key is easily retrievable, an attacker can use it to gain unauthorized remote access as root.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use exploit/linux/ssh/f5_bigip_known_privkey
msf exploit(f5_bigip_known_privkey) > show targets
    ...targets...
msf exploit(f5_bigip_known_privkey) > set TARGET < target-id >
msf exploit(f5_bigip_known_privkey) > show options
    ...show and set options...
msf exploit(f5_bigip_known_privkey) > exploit

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
