: The function replaces all single quotes, even those already preceded by a backslash.

The Security Shepherd continues to be an invaluable resource for the cybersecurity community, providing a safe, legal, and engaging environment to learn the ropes of web application security. If you found Challenge 5 instructive, continue progressing through the remaining SQL injection levels. Each one builds upon the last and deepens your understanding of how attackers think—and how defenders must think to stop them.

Increment N until you get "Valid". For example:

The in the OWASP Security Shepherd platform is a specialized training exercise. It is designed to teach security professionals how to bypass flawed input sanitization mechanisms. It focuses specifically on the vulnerability known as SQL Injection Escaping . url = "http://target-shepherd

The UNION operator combines the result sets of two or more SELECT statements. To use it, two conditions must be met:

If the query returns a row, login succeeds.

SQL Injection Challenge 5 in OWASP Security Shepherd effectively demonstrates that filtering simple keywords ( OR , AND , SELECT ) is insufficient. Attackers can use alternative tautologies, comment syntax, and blind techniques to bypass login and extract sensitive data. The challenge reinforces that the only reliable defense against SQL injection is the use of parameterized queries, not blacklisting.

The in OWASP Security Shepherd is a masterclass in the dangers of "black-box" security logic. While many earlier challenges focus on simple quote escapes, Challenge 5—often referred to as the Escaping Challenge —introduces a flawed sanitation mechanism that actually creates a vulnerability where it intended to fix one. The Illusion of Safety: Broken Escaping : The function replaces all single quotes, even
