First login into you WHM with the root login details and run following command

[[email protected]]# /usr/local/cpanel/bin/rebuild_phpconf current

If server is Suexec then you would have the below information ::

==============
DEFAULT PHP: 5
PHP4 SAPI: suphp
PHP5 SAPI: suphp
SUEXEC: enabled

==============

If you are not sure about Shell .Login into your WHM and in the menu find Configure PHP and SuExec

Select the drop down box for PHP 4/5 Handler and if beside that it says suPHP then the sever is SuExec enabled.

If you dont have server login details or WHM access, then you can create a php file under your account from cPanel >> File Manager and change the permissions on that file to 777 and open it in a browser. If it gives 500 Internal Server Error, then most probably running suPHP.

As well as you can also create the phpinfo page under your account from your cPanel >> File manager For ex. phpinfo.php with the following code

After creating phpinfo.php page browse it http://yourdomainname.com/phpinfo.php and if it shows Server API = Apache then server is not running PHP in Suexec mode and if Server API = CGI the server is running PHP in Suexec mode.
