Consider that by using JOINs and SELECTing from system tables (like mysql.innodb_table_stats), an attacker who starts with a SELECT injection and no other knowledge of your database can map your schema and then exfiltrate the entirety of the data that you have in MySQL.
2 Νοε 2020 · SQL Injection is a well-known technique used to attack SQL-based applications. In this article, we’ll focus on examples showing how you could exploit database vulnerabilities using this technique, while in the next article we’ll talk about ways how you can protect your application from such attacks.
SQL Injection is a type of vulnerability that occurs in an application's database when an attacker can insert or "inject" SQL commands into a query. This can allow the attacker to view, manipulate, or delete data in the database.
With PHP/MySQL application can allow for query stacking if you use the mysqli::multi_query() or mysqli_multi_query() functions. You can exploit these systems using sub-select, union-selects, blind sql injection, into outfile, or loadfile().
This SQL injection cheat sheet contains examples of useful syntax that you can use to perform a variety of tasks that often arise when performing SQL injection attacks.
SQL injection usually occurs when you ask a user for input, like their username/userid, and instead of a name/id, the user gives you an SQL statement that you will unknowingly run on your database. Look at the following example which creates a SELECT statement by adding a variable (txtUserId) to a select string.
