Attack vectors An attacker can overwrite or restore files to locations they do not have write privileges to. This can be accomplished via API or via the User Interface.
Description of the vulnerability When Code42 restores a file, it restores the file as the context of the Code42 service which is running as root, instead of the context of the user who launched the user interface. This only affects you if you are running a system installed CrashPlan, not a user installed CrashPlan. An attacker can craft a restore request to restore a file through CrashPlan to a location they do not have privileges to write.
