Advanced SQL Injection Techniques for Ethical Hackers and BB Hunters — By nav1n
1 min read
Summary
This article series aims to provide ethical hackers and bug hunters with advanced SQL Injection techniques to test and mitigate database vulnerabilities effectively.
It is essential to use these techniques responsibly and within legal and authorized testing scenarios, as they can potentially compromise database systems.
The first part of the series explores advanced error-based SQL injection, union-based injection, second-order SQL injection, and various combinations of these techniques.
Payloads are provided to elicit detailed errors, extract data from multiple queries or databases, and combine multiple techniques to strengthen effectiveness and obfuscation.
These techniques can be used to enumerate database details, fingerprinting, and bypassing web application firewalls (WAFs).
Automation and custom scripts, such as Python, can efficiently perform advanced union-based injections.
Subsequent parts will continue to explore advanced union-based SQL injection, boolean-based injection, advanced enumeration, and exploiting advanced scenarios, such as stored procedures, out-of-band SQL injection, and leveraging privileges.
