The Everest Backup – WordPress Cloud Backup, Migration, Restore & Cloning Plugin plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 2.3.13. This is due to insufficient validation of user supplied input before it is executed. This makes it possible for unauthenticated attackers to execute arbitrary code on the server.
