Wordpress is a free and open-source content management system (CMS) based on PHP and MySQL. WordPress uses PHPMailer, which is a PHP class used for sending email from PHP. PHPMailer provides an interface to the systemβs mail transfer agent (MTA), such as Sendmail, Postfix, or Exim. Exim4 is the default MTA installed on newer Debian and Ubuntu systems.
PHPMailer class mailSend() function is vulnerable to command injection due to failure to properly sanitize the destination email address. Exploiting this vulnerability in WordPress along with Eximβs expansion testing mode allows remote code execution.
Upgrade to WordPress Core version 4.7.1 or later to obtain an updated version of PHPMailer.

Exploit works on WordPress Core 4.6 and probably other versions before 4.7.1.
The target must have wget or curl and the Exim mail transfer agent.
