-5025 Order By 1# 【Limited Time】

Ensure the database user account used by the web application has limited permissions.

Use allow-lists to ensure inputs match expected formats (e.g., ensuring an ID is always a positive integer). -5025 ORDER BY 1#

The number 1 refers to the first column in the SELECT statement. Ensure the database user account used by the

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

This is the terminator . It attempts to break out of the developer's intended string literal. If the application does not sanitize input, the database engine will see this quote and assume the original command has ended, allowing the attacker to append their own logic.

This makes it easier to see how the database reacts when the injected code is added. ORDER BY 1 : This is the structural probe .

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.
