If you are looking for more specific help with your current progress: Which are you seeing? Are single quotes being stripped out? Do you have the table names yet?
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 .
: Use a UNION SELECT statement with dummy values to see which columns appear on the screen. Example: 1' UNION SELECT 1,2,3-- sql+injection+challenge+5+security+shepherd+new
: If quotes are blocked, use 0x61646d696e instead of 'admin' . Remediation and Best Practices
: Ensure the database user account used by the web app has only the permissions it needs. If you are looking for more specific help
: 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.
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.

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.
