Description

pfSense, a free BSD based open source firewall distribution, version <= 2.2.6 contains a remote command execution vulnerability post authentication in the _rrd_graph_img.php page. The vulnerability occurs via the graph GET parameter. A non-administrative authenticated attacker can inject arbitrary operating system commands and execute them as the root user. Verified against 2.2.6, 2.2.5, and 2.1.3.

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/unix/http/pfsense_graph_injection_exec
msf exploit(pfsense_graph_injection_exec) > show targets
    ...targets...
msf exploit(pfsense_graph_injection_exec) > set TARGET < target-id >
msf exploit(pfsense_graph_injection_exec) > show options
    ...show and set options...
msf exploit(pfsense_graph_injection_exec) > 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.
