The input string explicitly starts with a raw backslash ( \ ) and a quote ( ' ).
Instead:
So we bypass AND by using * :
SELECT * FROM users WHERE username="admin" AND (password="" OR ""="");
Thus, the robust solution: Use ' || '1'='1 in password field. Sql Injection Challenge 5 Security Shepherd
To help you get through this specific level, could you tell me: What do you get when you submit a single quote? Are you seeing a login box or a search field ?
Let's look at how the application interprets a standard attack query vs. a manipulated bypass query under a broken escape filter: User Input What the Filter Produces Database Interpretation ' OR 1=1; -- \' OR 1=1; -- Literal string starting with a quote \' OR 1=1; -- \\\' OR 1=1; -- An escaped backslash ( \\ ) + a live single quote ( ' ) Exploit Succeeds Step-by-Step Walkthrough: Extracting the VIP Code Step 1: Mapping the Attack Surface The input string explicitly starts with a raw
