Description

This module exploits a vulnerability found in ZeroShell 2.0 RC2 and lower. It will leverage an unauthenticated local file inclusion vulnerability in the "/cgi-bin/kerbynet" url. The file retrieved is "/var/register/system/ldap/rootpw". This file contains the admin password in cleartext. The password is used to login as the admin user. After the authentication process is complete it will use the RunScript action to execute the payload with root privileges.

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/webapp/zeroshell_exec
msf exploit(zeroshell_exec) > show targets
    ...targets...
msf exploit(zeroshell_exec) > set TARGET < target-id >
msf exploit(zeroshell_exec) > show options
    ...show and set options...
msf exploit(zeroshell_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.
