靶机的IP:10.10.10.86 

 

信息的获取

用Nmap进行扫描

nmap -sC -T5 10.10.10.86

 

发现靶机开启了80,22,21,8080端口

我们先访问下80端口

尝试用hydra来爆破账号密码，以及用了BURP进行SQL注入FUZZ发现都没有什么进展

hydra -L username.txt -P /usr/share/wordlists/rockyou.txt -vV -t 64 10.10.10.86 http-post-form "/login:username=^USER^&password=^PASS^:Login failed" -s 80

 

 

 

试下FTP，先用MSF看下是否运行匿名访问FTP

发现是可以的，那我们来访问下

如果你的kali没有ftp命令的话 可以用 apt-get install ftp

或者你用浏览器访问 ftp://10.10.10.86也可以

 

这里我们看到里面就只有一张图片 我们下载来看下

get dab.jpg

图片如下：

 

这里猜测可能是隐写术

这里我们用steghide工具来查看下

发现有隐藏数据，这里需要输入密码，这里我们尝试留空发现内容。

然后我们吧内容提取出来

steghide extract -sf dab.jpg 

因为这里的密码为空，我们就不用-p参数了

然后家目录下会出现dab.txt的文件

恩看来被耍了。

 

那我们在看看8080端口

出现 Access denied: password authentication cookie not set

 

我们试着对80和8080 进行目录爆破

这里我用gobuster

gobuster -u http://10.10.10.86/ -w /usr/share/wordlists/dirb/common.txt -t 100

gobuster -u http://10.10.10.86:8080/ -w /usr/share/wordlists/dirb/common.txt -t 100

 

只有80端口额外发现了logout，8080没有什么发现

后来看了别人的wp发现，自己在爆破那不忘记加-f 就是破解到一个密码就停止而且我也加了-vV显示详细过程，导致我之前可能是破解出密码，但是没看到就草草关掉了hydra

hydra -l admin -P /usr/share/wordlists/rockyou.tx64 10.10.10.86 http-post-form "/login:username=^USER^&password=^PASS^:Login failed" -s 80

这里我试了2种，爆破出2哥账号密码

 

那我们登陆下

查看源码发现这一句话

这个数据表会被加载到mysql中去

 

我们在回到8080端口

我们抓包然后添加名为password的cookie字段

这里我们用下wfuzz进行爆破下

字典地址:https://github.com/sdfzy/SecLists

wfuzz -u http://10.10.10.86:8080/ -w /usr/share/SecLists-master/Passwords/darkweb2017-top1000.txt  -b password=FUZZ

这里我们看到不正确的包的chars是324 所以我们还要加个--hh过滤下，只显示正确的结果

wfuzz -u http://10.10.10.86:8080/ -w /usr/share/SecLists-master/Passwords/darkweb2017-top1000.txt --hh 324  -b password=FUZZ

-b password: 指定请求的cookie参数password，可指定多个cookie

这里我们发现了密码但是还有一些324没过滤掉

我们首先看到的是：“缓存引擎的状态：在线”

缓存引擎？经过一些谷歌搜索后，我们将找到一个名为memcached的软件

https://www.cnblogs.com/loveis715/p/4681643.html

https://downloads.mysql.com/docs/mysql-memcached-en.a4.pdf

memcached是一个简单，高度可扩展的基于密钥的缓存，可以在专用或备用RAM可供应用程序快速访问的任何地方存储数据和对象，而无需经过分析或磁盘I / O层。要使用，请在一个或多个主机上运行memcached命令，然后使用共享缓存来存储对象。第1页
 

默认情况下，memcached使用以下设置：•64MB的内存分配•使用端口11211侦听所有网络接口上的连接•支持最多1024个并发连接 - 第5页

所以我们知道memcached在端口11211上运行，让我们尝试对其他端口进行测试，出错

然后我们对11211测试

说明我命发送的命令是错误的，但是端口是正常的

memcached的命令集:https://lzone.de/cheat-sheet/memcached

然后我们 get users

我们把数据保存在users.txt中[注意这里不要把其他无关的数据复制进来]

然后我们整理下数据 

我们将使用一个名为json.tool的python模块来获得更清晰的输出

cat users.txt | python -m json.tool > users2.txt

 

然后我们把 文本里面的账号内容分离出来

cat users2.txt | cut -d ":" -f 1 | cut -d '"' -f 2 > usernames.txt

然后我们用msf的ssh_enumusers模块进行ssh用户枚举

这里我选这个genevieve，当然你也可以选择其他存在的用户

 

 

然后我们再找到对应的hash

cat users2.txt | grep genevieve

再放到一个文件里面

 

然后我们去破解下

然后我们就用这个去登陆ssh

genevieve：Princess1

 

拿到user的flag

 

我们在执行下  sudo -l 看下自己的权限

我们看到我们可以以root身份 /usr/bin/try_harder身份运行这个二进制文件

这个时候我们就是root身份了

但是这个会再我们每执行玩一次命令之后退出，所以没什么用

 

我们搜下suid文件

genevieve@dab:/usr/bin$ find / -perm -4000

我们试着调用这个文件

但是被要求输入密码 我们逆向下找到密码

我们把文件下载过来

然后我们将使用radare2

radare2 myexec 
 
aaa 
 
pdf @ main

密码是s3cur3l0g1n，让我们回去试试看

 

 

劫持动态链接共享对象库并获取root权限

我们之前在执行二进制文件时看到了： 

seclogin() called

所以理论上，如果我们可以替换libseclogin.so

另一个并链接到它，二进制文件将以root身份执行它。让我们测试一下。

我们在/home/genevieve/中 生成一个bash小程序，并调用它

这个程序的意思是，把uid和gid都设置为0（root）,然后执行/bin/bash

之后我们将编译它

gcc -fPIC -shared -o /home/genevieve/libseclogin.so /home/genevieve/exploit.c

会出现警告，可以忽略

 

假东西准备好了

我们将cd到/etc/ld.so.conf.d，并创建一个exploit.conf文件，并把我们的路径写进去了。

/home/genevieve/

然后执行 ldconfig 加载这个配置文件

替换成功，然后我们执行后就会得到root shell
