Successful SQL injection often requires a payload tailored to a specific SQL database system. Payload usability is indicated as follows: M = works on MySQL S = works on SQL Server P = works on PostgreSQL O = works on Oracle L = works on SQLite + = works on potentially other databases ...
然后网上公开的基本上都是2.x版本的payload,对于sql injection,除了文中提到的insert_ads,insert_bought_notes函数同样存在漏洞: $sql='SELECT u.user_name, og.goods_number, oi.add_time, IF(oi.order_status IN (2, 3, 4), 0, 1) AS order_status '.'FROM '.$GLOBALS['ecs']->table('order_in...
This allows an attacker to infer if the payload used returned true or false, even though no data from the database is returned. Out-of-band SQLi Out-of-band SQL Injection is not very common, mostly because it depends on features being enabled on the database server being used by the ...
“blind SQL Injection attacks”). Instead, an attacker is able to reconstruct the database structure by sending payloads, observing the web application’s response and the resulting behavior of the database server. The two types of inferential SQL Injection are Blind-boolean-based SQLi and Blind...

这是一个sql二次注入的题。所谓二次注入就是先在非注入点构造payload,程序会存储这个payload。然后程序会在注入点调用这个payload进行数据库操作。

sqlmap needs to add this injection payload syntax: vulnerableparameter=2,if(substring(user(),1,1)='a',SLEEP(1),1) I went through all the logs of used payloads by sqlmap when using --level=5 --risk=3 -v 3 and not once did I see that being used, that is the only syntax that ...
