What does drop table SQL injection do?
I used some vulnerability scanners to check a site of mine, and an instance of blind SQL injection was returned. However, when I try to exploit this vulnerability by entering the following into the address bar, nothing happens: http://www.example.com/articles.php?id=-1' or 68 = '66; DROP ALL TABLES; -- I don't see why this isn't working. What is the correct text I must enter into the address bar to drop all the tables ?
The vast majority of web applications do not allow query stacking. The Drop table SQL injection 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(). SQLMap and Havij are both tools that automate the exploitation of SQL Injection. SQLMap is a great tool with a wide range of features, and supports a wide verity of injections and DBMS'es.
