PHPMailer Sendmail Argument Injection
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.

- Collect and share all the information you need to conduct a successful and efficient penetration test
- Simulate complex attacks against your systems and users
- Test your defenses to make sure they’re ready
- Automate Every Step of Your Penetration Test
Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
