WordPress WP Symposium 14.11 Shell Upload

Description

WP Symposium Plugin for WordPress contains a flaw that allows a remote attacker to execute arbitrary PHP code. This flaw exists because the /wp-symposium/server/file_upload_form.php script does not properly verify or sanitize user-uploaded files. By uploading a .php file, the remote system will place the file in a user-accessible path. Making a direct request to the uploaded file will allow the attacker to execute the script with the privileges of the web server.

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