Description

This module exploits a vulnerability in ZEN Load Balancer version 2.0 and 3.0-rc1 which could be abused to allow authenticated users to execute arbitrary code under the context of the 'root' user. The 'content2-2.cgi' file uses user controlled data from the 'filelog' parameter within backticks.

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