Anyway I wanted to push myself to escalate this XSS to full instance take over, so was time to escalate this simple alert box.Escalation:So, my first taught was that if the XSS was able to run in the same context that all files, maybe I can run a simple GET to extract any “local” file, but it was not that easy, also another problem that I notice is that the UI Theia editor part for the editor was running in some instance that is different for the actual “command line terminal”So luckily the UI Theia instance part has the private key in the root of the instance, and we just needed to navigate to a new workspace and set / (root) to see that key, anyway sadly there is no screenshot for that, but you have my word, once loaded the workspace “/” you can see that “id_cloudshell” file, So in the end the solution for reading those files via HTTP GET on javascript was using this 2 endpoints:1.- First, https://’ + location.host + ‘/files/?uri=’This to get the id for any uri, per example /files/?uri=file:///etc/hosts, responses something like {id: “5147084a-XXXX-43a9-afb0-bb8a126f1162”} 2.- And then use https://’ + location.host + ‘/files/download/?id=’ with the id /files/download/?id=5147084a-XXXX-43a9-afb0-bb8a126f1162 and getting the actual file content, Putting all together :Google Cloud Shell has an option to import GitHub repositories into Google Cloud shell instances with 1 click , so the main idea was:1.- Create a malicious git repository to store that malicious script in the read.md file2.- We can also put the open in google cloud shell button in the same file md file, 3.- Then trick the user to import that git repository to his google cloud shell instance 4.- Once the read.md file renders we stole the /etc/hosts file to construct the public domain to access that cloudshell instance and also the private key /../id_cloudshellthe hostname is “cs-6000-devshell-vm-XXXXXXXX-XXXX-XXXXX-XXXXX”, we delete the cs-6000 part and append .cloudshell.dev, getting something like this devshell-vm-XXXXXXXX-XXXX-XXXXX-XXXXX.cloudshell.dev that is public accessible for anyone5.- Since we know that the root user is always present user in Linux we can use that to login in via ssh6.- with devshell-vm-XXXXXXXX-XXXX-XXXXX-XXXXX.cloudshell.dev (public domain) we can actually get the IP from devshell-vm-XXXXXXXX-XXXX-XXXXX-XXXXX.cloudshell.dev making a ping and then do some port scanning, (after that we discovered that the ssh service was running on 6000 port )7.- Profit, knowing the public domain hostname, the ssh port, the user root, and the private key we just needed to login in and run any command that we want‘ssh -i id_cloudshell -p 6000 root@devshell-vm-XXXXXXXX-XXXX-XXXXX-XXXXX.cloudshell.dev‘Final read.me file code, Extracted from Google VRP’s report: (the actual Google VRP report), Summary: Google cloud shell instance take over (as root), 1.- Setup an SSL server that you own in any port, I will use ngrok + nc combo over port 55555, 2.- Visit https://github.com/omespino/gcs_instace_takeover and click open in Google Cloud Shell, 3.- Wait to load everything and then click the preview button for the .md files (you need to set up the attacker server that you own before de preview), 4.- Receive 2 google vm’s files: ‘/etc/hosts’ and the private key ‘../id_cloudshell’ (scape the container with ‘../’ )        4.1: for the private key you need to replace \n for jumplines and save it as ‘id_cloudshell’        4.2: the hostname is “cs-6000-devshell-vm-XXXXXXXX-XXXX-XXXXX-XXXXX”, we delete the cs-6000 part and append .cloudshell.dev, getting something like this devshell-vm-XXXXXXXX-XXXX-XXXXX-XXXXX.cloudshell.dev, 5.- login as root on ssh over port 6000        ‘ssh -i id_cloudshell -p 6000 root@devshell-vm-XXXXXXXX-XXXX-XXXXX-XXXXX.cloudshell.dev‘, 6.- w00t!!!
