This will run DROP members SQL sentence after normal SQL Query. SELECT * FROM products WHERE id = 10 DROP members.Can someone clarify? Stacked SQL Injection Attack Samples Normally MySQL supports stacked queries but because of database layer in most of the configurations it’s not possible to execute a second query in PHP-MySQL applications or maybe MySQL client supports this, not quite sure. PHP – MySQL doesn’t support stacked queries, Java doesn’t support stacked queries ( I’m sure for ORACLE, not quite sure about other databases). Green: supported, dark gray: not supported, light gray: unknown Language / Database Stacked Query Support Table This is very useful in every injection point, especially in SQL Server back ended applications.Įnds a query and starts a new one.
