Time-based extraction from a silent endpoint

Injection is untrusted input reaching an interpreter as code rather than as data. When a value you supply is concatenated into a SQL query or a shell command, characters that mean something to that interpreter let you change what it does — read tables you should not, or run commands the app never intended.

This lab: Time-based extraction from a silent endpoint. Break out of a query or a shell command through unescaped input.

Work it against your own copy of the target. When you have the flag, submit it below.

Find an input that is built into a query or a command, break out of the data and into the syntax, and extract something you should not be able to reach. Capture the flag it exposes.
