25 Minutes, 4 SQL Problems: No Code Execution Allowed!

In a recent SQL assessment, participants faced a unique challenge: they were not allowed to run their code to check the results. The test consisted of four problems, split evenly between medium and hard difficulties, to be completed within 25 minutes. These problems often required complex operations such as multiple joins and Common Table Expressions (CTEs). Participants managed to complete three out of the four problems but received no feedback on the accuracy of their solutions. Instead, the assessment focused solely on the logical soundness of the code. This approach differs from common practice resources like LeetCode and Data Lemur, where running code is typically permitted.

While life hits hard due to decisions made in seconds, I always believed that sharing is caring. Despite some suggesting I open a course on SQL injection, I will never do it. Here’s how I exploited SQL injection on applications with limited verbose errors and no single quotes

You’ve found an SQL injection vulnerability But keywords such as SELECT, SLEEP, and UNION are all filtered and removed from your input… What do you use to prove your SQL injection?

Check your joins or any logic operations in your SQL statements. Look up using EXPLAIN ANALYZE and/or Performance Schema to ascertain what’s holding you back.
