Gaara: 1 ~ VulnHub

writeup walkthrough

Enumeration
Enumerate the web application for a username.

Foothold
Brute-force the SSH service. You can get away with a smaller wordlist if it’s the right one.

Privilege Escalation
Check for SUID permissions. It is very straight-forward to exploit.

一、端口扫描

nmap 192.168.222.142
Starting Nmap 7.93 ( https://nmap.org ) at 2023-08-11 09:17 CST
Nmap scan report for 192.168.222.142
Host is up (0.29s latency).
Not shown: 998 closed tcp ports (conn-refused)
PORT   STATE SERVICE
22/tcp open  ssh
80/tcp open  http

nmap -sC -sV -p 22,80 192.168.222.142  
Starting Nmap 7.93 ( https://nmap.org ) at 2023-08-11 09:30 CST

Nmap done: 1 IP address (1 host up) scanned in 22.98 seconds

nmap -p- 192.168.222.142 # 全面扫描端口
nmap -sC -sV -p 22,80 192.168.222.142

-sC：此标志启用默认脚本扫描，该扫描针对开放端口运行一组脚本，以收集有关在这些端口上运行的服务的其他信息。
-sV：此标志启用版本检测，该检测尝试确定在开放端口上运行的服务的版本。
-p 22,80：指定要扫描的端口列表，特别是端口 22 （SSH）和 80 （HTTP）。

22为ssh端口,用于SSH远程链接,攻击方向为爆破,SSH隧道及内网转发文件存储

80为web服务端口,一般进行Web攻击,爆破,对应服务器版本漏洞

二、目录枚举

gobuster dir -u http://192.168.222.142 -w /usr/share/wordlists/dirbuster/directory-list-2.3-medium.txt  

gobuster dir -e -u http://192.168.222.142/ -w /usr/share/wordlists/dirbuster/directory-list-2.3-medium.txt

自带的字典在/usr/share/dirbuster/wordlists下
