Using typical sleep-based payloads (' WAITFOR DELAY '0:0:5' --) yields no delay. This suggests either:
However, the challenge hint explicitly mentions xp_dnsresolve, confirming the back-end is Microsoft SQL Server with extended stored procedures enabled.
Headline: Automated tools failed me. Here is how I solved Security Shepherd SQLi Challenge 5. 🛡️
I’ve been grinding through the OWASP Security Shepherd challenges to sharpen my web exploitation skills. Levels 1 through 4 were smooth sailing, but Challenge 5 was a wall.
Why? Because my usual "lazy" habit of firing up SQLMap didn't work. The application had a filter in place that blocked my standard payloads.
The Lesson: This challenge forces you to understand how SQL parsers work versus how input filters work. It’s a game of "Simon Says" with the database.
I had to manually craft a payload that bypassed the keyword filter. It was a great reminder that while automation is fast, manual testing is deep. If you rely solely on tools, you will miss vulnerabilities that require a creative touch.
Key Takeaway for Devs: If you are blocking specific keywords (like "SELECT" or "UNION") to stop hackers, you are doing it wrong. Blacklists are fragile. A simple encoding trick or case swap can render them useless.
Use Parameterized Queries. They treat user input as data, not executable code, rendering these injection tricks useless. sql+injection+challenge+5+security+shepherd+new

The sql injection challenge 5 security shepherd new is not just a CTF problem; it is a phylosophical lesson in cybersecurity. It demonstrates that security through obscurity (case filtering, space stripping) is a fragile shield. Attackers armed with patience, boolean logic, and a basic understanding of SQL syntax will always find a way through.
If you have successfully exploited this challenge, you have moved beyond being a script kiddie. You now understand blind boolean-based injection, mixed-case keyword evasion, and comment-based whitespace bypasses.
Keep practicing. Secure your own applications. And remember: The Shepherd does not just guard the sheep; the Shepherd tests the wolves.
Need the exact solution for your specific instance of Security Shepherd? Ensure your version is updated to the "new" standard. The payloads above (using mixed-case /eXpLoIt/ syntax) currently bypass all versions as of 2025.
SQL Injection 5 challenge in OWASP Security Shepherd is a practical exercise in bypassing modern input sanitisation techniques. Unlike earlier levels that might be vulnerable to simple ' OR 1=1 --
payloads, this challenge typically involves a scenario where common characters are escaped or filtered, requiring more creative exploitation. Core Objective The primary goal is to retrieve a VIP Coupon Code Using typical sleep-based payloads ( ' WAITFOR DELAY
to purchase a "troll" item without being charged, which subsequently reveals the session's result key. This simulates a real-world e-commerce vulnerability where sensitive pricing or discount logic can be manipulated through the database backend. Understanding the Vulnerability
In many versions of this challenge, the application attempts to protect itself by "escaping" single quotes (replacing
). Paradoxically, this security measure can be its downfall if not implemented correctly: The Escape Trap
: If the escaping function is applied globally, an attacker can input a backslash before a quote (e.g., The Bypass
: The application might escape the attacker's backslash, turning it into a literal backslash (
), which then leaves the subsequent single quote unescaped and active in the SQL command. The Payload : A common successful payload for this level is \' OR 1=1; -- or variations like
depending on whether the query uses single or double quotes. Exploitation Strategy To solve the challenge effectively, follow these steps: Identify the Injection Point couponCode
parameter in the purchase or check-out request is the most likely target. Analyse the Response The sql injection challenge 5 security shepherd new
: Observe how the application handles different characters. If a single quote returns a generic error, try escaping it yourself to see if you can "break out" of the string literal. Automate for Efficiency
: For "blind" scenarios where data isn't directly echoed back, tools like
can be used to dump the database schema and retrieve the actual coupon codes. Final Execution : Once the VIP code is retrieved (e.g., via a UNION-based injection
), submit it in the coupon field with a quantity of at least one to trigger the "zero charge" logic and receive your key. Key Learnings This challenge highlights that denylisting
or simple string replacement is rarely a sufficient defence against SQL injection. Developers should instead use parameterised queries
or prepared statements, which separate the SQL command from the user-provided data entirely, ensuring that input is always treated as a literal value rather than executable code. step-by-step walkthrough
