Description

PHPMailer versions up to and including 5.2.19 are affected by a
vulnerability which can be leveraged by an attacker to write a file with
partially controlled contents to an arbitrary location through injection
of arguments that are passed to the sendmail binary. This module
writes a payload to the web root of the webserver before then executing
it with an HTTP request. The user running PHPMailer must have write
access to the specified WEB_ROOT directory and successful exploitation
can take a few minutes.
