靶机渗透练习83-The Planets：Venus

2023-05-16

靶机描述

靶机地址：https://www.vulnhub.com/entry/the-planets-venus,705/

Description

Difficulty: Medium

Venus is a medium box requiring more knowledge than the previous box, “Mercury”, in this series. There are two flags on the box: a user and root flag which include an md5 hash. This has been tested on VirtualBox so may not work correctly on VMware. Any questions/issues or feedback please email me at: SirFlash at protonmail.com

一、搭建靶机环境

攻击机Kali：

IP地址：192.168.56.100

靶机：

IP地址：192.168.56.101

注：靶机与Kali的IP地址只需要在同一局域网即可（同一个网段,即两虚拟机处于同一网络模式）

该靶机环境搭建如下

  1. 将下载好的靶机环境，导入 VritualBox，设置为 Host-Only 模式
  2. 将 VMware 中桥接模式网卡设置为 VritualBox 的 Host-only

二、实战

2.1网络扫描

2.1.1 启动靶机和Kali后进行扫描

方法一、arp-scan -I eth0 -l （指定网卡扫）

arp-scan -I eth0 -l

⬢  The Planets: Venus  arp-scan -I eth0 -l
Interface: eth0, type: EN10MB, MAC: 00:50:56:27:27:36, IPv4: 192.168.56.102
Starting arp-scan 1.9.7 with 256 hosts (https://github.com/royhills/arp-scan)
192.168.56.100  08:00:27:fd:e6:e4       PCS Systemtechnik GmbH
192.168.56.101  08:00:27:94:93:1d       PCS Systemtechnik GmbH

2 packets received by filter, 0 packets dropped by kernel
Ending arp-scan 1.9.7: 256 hosts scanned in 2.286 seconds (111.99 hosts/sec). 2 responded
方法二、masscan 扫描的网段 -p 扫描端口号

masscan 192.168.184.0/24 -p 80,22

方法三、netdiscover -i 网卡-r 网段

netdiscover -i eth0 -r 192.168.184.0/24

方法四、等你们补充

2.1.2 查看靶机开放的端口

使用nmap -A -sV -T4 -p- 靶机ip查看靶机开放的端口

⬢  The Planets: Venus  nmap -A -sV -T4 -p- 192.168.56.101 
Starting Nmap 7.92 ( https://nmap.org ) at 2022-04-24 14:26 CST

Task Completed

我们找到一个 /admin 目录

访问：http://192.168.56.101:8080/admin

它将我们重定向到 Django 管理登录门户：http://192.168.56.101:8080/admin/login/?next=/admin/

image-20220424152411289

但是当我们尝试一个随机的用户名和密码时，我们得到一个内部服务器错误

image-20220424152507580

回到第一个登录表单，我们注意到如果我们尝试使用无效用户登录，我们会收到“无效用户名”警告，但如果我们尝试以访客身份登录但提供的密码不正确，我们会收到“无效密码”，利用这一点，我们可以尝试使用 hydra 枚举其他有效用户。

用户字典使用https://github.com/jeanphorn/wordlist/blob/master/usernames.txt

hydra -L usernames.txt -p pass -s 8080 192.168.56.101 http-post-form "/:username=^USER^&password^PASS^:Invalid username."

成功拿到两个新用户 venus和magellan

好的，让我们试着找出 venus 和 magellan 的密码！

当我们以访客用户身份登录时，会设置一个 auth cookie，

现在我们向服务器发出的每个请求都会发送该cookie以验证我们是否已通过身份验证。

image-20220424162247107

发现base64加密，解密发现不一样的东西

image-20220424162559947

得到guest:thrfg

现在我们有了用户名和一些乱码，可能是编码密码。

现在我们将专注于用户名。如果我们为之前找到的一位用户更改它，将其编码为 base64 并用原始 cookie 替换它会怎样？

总结

本靶机通过利用登录报错，并利用hydra枚举用户名，然后通过更改cookie来获取用户密码，ssh登录后，通过信息收集找到可利用的suid程序，最后利用已经漏洞提权

  1. 信息收集
  2. dirsearch目录扫描
  3. hydra枚举用户名
  4. 更改cookie获取用户密码
  5. rot13解密
  6. suid提权—cve-2021-4034
