To solve this challenge, follow these logical steps to identify the number of columns and extract the data.
In Challenge 5, the application likely takes a user-provided string and inserts it directly into a SQL query. The developer has likely implemented a basic security measure, such as filtering for specific characters like ' (single quotes) or keywords like OR .
: Once you have the table and column names, use a final UNION SELECT to pull the flag. Key Payload Examples sql+injection+challenge+5+security+shepherd+new
Understanding and solving SQL Injection Challenge 5 in Security Shepherd requires a grasp of how to bypass basic filters and extract data from a backend database. This challenge typically focuses on demonstrating how developers try to sanitize inputs—and how those attempts can still be circumvented.
🚀 : If the application strips out the word OR or SELECT , try using different casing (e.g., sElEcT ) or doubling the keyword (e.g., SELSELECTECT ) if the filter only runs once. Standard Bypass : ' OR '1'='1 Union Discovery : -1' UNION SELECT 1,2,database(),4-- To solve this challenge, follow these logical steps
However, if the filter is not comprehensive, an attacker can use alternative syntax to achieve the same result. For example, if single quotes are blocked, you might use hexadecimal encoding or different query structures to keep the syntax valid while still injecting malicious commands. Step-by-Step Walkthrough
: Use the ORDER BY clause to find how many columns the original query is selecting. 1' ORDER BY 1-- 1' ORDER BY 2-- Keep increasing the number until you get an error. : Once you have the table and column
: Use parameterized queries so user input is never treated as executable code.
