An is a specifically crafted string of malicious SQL code that an attacker inserts into a vulnerable application's input field. Unlike standard data (like a username or password), a payload contains SQL syntax designed to manipulate the backend database query, potentially leading to unauthorized data access, modification, or even complete system takeover. How SQL Injection Payloads Work
If an attacker enters the payload admin' -- into the username field, the query transforms into: SELECT * FROM users WHERE username = 'admin' --' AND password = '...'; sql injection payload
For example, a legitimate login query might look like this: SELECT * FROM users WHERE username = 'alice' AND password = 'password123'; An is a specifically crafted string of malicious
Security researchers and attackers categorize payloads based on how they interact with the database and how the results are returned. What is SQL Injection (SQLi) and How to Prevent Attacks What is SQL Injection (SQLi) and How to
The -- sequence is an SQL comment that tells the database to ignore the rest of the query, effectively bypassing the password check and granting access to the admin account. Common Types of SQL Injection Payloads
SQL injection occurs when an application fails to separate user-provided input from the program's intended SQL instructions. When this untrusted input is concatenated directly into a query, the database engine interprets the malicious payload as part of the command itself.
