-5025 Order By 1# Page

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#

This is the gold standard. It treats user input strictly as data, never as executable code. This is the comment character for MySQL

SQL Injection is a vulnerability where an attacker interferes with the queries an application makes to its database. The payload "-5025 ORDER BY 1#" is an "Inference" or "Error-based" probe used to determine the structure of a database table without having direct access to the source code. This is the gold standard

Here is a short technical paper outlining its structure, purpose, and how to defend against it. 1. Introduction

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.

SELECT name, email FROM users WHERE id = "-5025" ORDER BY 1#";
