-5025 Order By 1# Site
Ensure the database user account used by the web application has limited permissions.
This is the comment character for MySQL. It tells the database to ignore everything that follows it in the original code. This prevents the "leftover" part of the developer’s query from causing a syntax error that would break the injection. 3. Execution Flow
Attackers increment this number (e.g., ORDER BY 2 , ORDER BY 3 ). When the database throws an error (e.g., "The ORDER BY position number 10 is out of range"), the attacker knows exactly how many columns the original query is fetching. -5025 ORDER BY 1#
SELECT name, email FROM users WHERE id = "-5025" ORDER BY 1#";
This is often a "false" or "null" value. By inputting a value that likely doesn't exist (like a negative ID), the attacker forces the application to return an empty result set or an error. This makes it easier to see how the database reacts when the injected code is added. ORDER BY 1 : This is the structural probe . Ensure the database user account used by the
Successful use of this payload is the first step in a larger attack. Once the number of columns is known, an attacker can use a UNION SELECT statement to: Extract usernames and passwords. Bypass authentication screens. Gain administrative access to the server.
This is the gold standard. It treats user input strictly as data, never as executable code. This prevents the "leftover" part of the developer’s
The string is a classic example of a SQL Injection (SQLi) payload, specifically used for database reconnaissance.
