SQL Injection 03

This exercise is one of our challenges on SQL Injections

< 1 Hr.


In this lab, you will explore an SQL injection vulnerability in a login form that requires the injected payload to return only one record. This challenge is part of the Essential Badge series, where similar injections were previously examined. Unlike earlier exercises, this one involves a safeguard that checks if the query returns more than one row; if it does, an error message is displayed.

The video walkthrough provides an in-depth explanation of the PHP code handling the login request. By analyzing the code, you will understand the structure of the SQL query and how it can be manipulated. The solution involves using the LIMIT keyword to ensure only one record is returned, thereby bypassing the developer's check and effectively logging in as any user.
