What to do

Solution: Zebra Printers running Link-OS v6.0 and later have a protected mode that protects the printer from this vulnerability. Activating this mode disables unauthorized changes and locks the current configuration until an administrator authorizes updates. By default, the secure mode is disabled as it is necessary to generate a password first. NOTE: the ZT410 industrial printer was discontinued on Oct 1st, 2020. The service and Support discontinuation dates are in September and December 2025 depending on region. Further information regarding security settings and best practices, including “Protected Mode”, can be found in the references. UPDATE: The vulnerability has been fixed by Zebra. The updated firmware version is Link-OS v7.3 which was released March 2025. The currently released version is Link-OS v7.4 which includes the fix that was released in the previous version.
