Continue Reading. The query that this code intends to execute follows: However, because the query is constructed dynamically by concatenating a So filling in random SQL commands and submitting the form will not always result in succesfull authentication. In-band SQLi - The attackers use the same communication channel to launch their attacks and collect results. See how our software enables the world to secure the web. You can craft your queries within the URL or combine multiple statements within the input fields and try to generate a response. Without minimizing the disastrous consequences this might have, it is important to mention that a SQL injection can have much bigger security impact than a login bypass.
