 · You will get familiar with the distinctive injection techniques to upload malicious PHP files in a web server and use them to have full access. Basic file upload using “Weevely” For file. In general, the most reliable way to detect whether command injection is possible is to use time-delay inference in a similar manner with which you might test for blind SQL injection. Visit the web page of the application that you are testing. Return to Burp and ensure "Intercept is on" in the Proxy "Intercept" tab. Hence, for command injection, we can have the following feedback channels: output (all the above examples except the last one use directly returned output, could as well be indirectly returned, e.g. visible in some other module, put into a file, sent via email and so on, all depending on what the vulnerable feature does and how it returns.
