We covered a Docker container running a web server that is vulnerable to server side request forgery. We used that vulnerability to execute system commands and gain access to sensitive information stored inside git commits. We learned that a Docker daemon runs on port 2375 but in order to probe and access that container we need to perform port knocking to open the port 2375. Afterwards, we mounted the complete host file system.. This was part of TryHackMe The GreatEscape.
