Скачать или смотреть Command Injection - Lab #4 Blind OS command injection with out-of-band interaction | Short Version

In this video, we cover Lab #4 in the Command Injection module of the Web Security Academy. This lab contains a blind OS command injection vulnerability in the feedback function.

The application executes a shell command containing the user-supplied details. The command is executed asynchronously and has no effect on the application's response. It is not possible to redirect output into a location that you can access. However, you can trigger out-of-band interactions with an external domain.

To solve the lab, we exploit the blind OS command injection vulnerability to issue a DNS lookup to Burp Collaborator.
