-5025 Order By 1# [ WORKING · 2025 ]
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.
The string is a classic example of a SQL Injection (SQLi) payload, specifically used for database reconnaissance.
Ensure the database user account used by the web application has limited permissions. -5025 ORDER BY 1#
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. It treats user input strictly as data, never as executable code. Successful use of this payload is the first
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.
Use allow-lists to ensure inputs match expected formats (e.g., ensuring an ID is always a positive integer). Gain administrative access to the server
Here is a short technical paper outlining its structure, purpose, and how to defend against it. 1. Introduction
