First upload a file named iamfedup.session which contains command to change the mode to 777
Now try with JSESSION ID iamfedup , which will automatically look for iamfedup.session
First Upload iamfedup2.session named file
then Call the iamfedup2 , this will automatically call for iamfedup2.session
(I messed up in between so I did the process again with new port i.e. 1234) Got the Reverse Shell
Getting user.txt
Simply run command to escape docker shell, by mounting /root of VirusBucket to /mnt, then add your ssh keys to authorized keys
After adding authorized keys , login with SSH into the machine
Finally we are the root.
Don’t forget to get your root.txt
