A vulnerability of authentication bypass has been found on a Zebra Technologies ZTC ZT410-203dpi ZPL printer. This vulnerability allows an attacker that is in the same network as the printer, to change the username and password for the Web Page by sending a specially crafted POST request to the setvarsResults.cgi file. For this vulnerability to be exploitable, the printers protected mode must be disabled.

Remedy

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.

Zebra Industrial Printers All Versions, Zebra printers are shipped with unrestricted end-user access to front panel options. If the option to use a passcode to limit the functionality of the front panel is applied, specially crafted packets could be sent over the same network to a port on the printer and the printer will respond with an array of information that includes the front panel passcode for the printer. Once the passcode is retrieved, an attacker must have physical access to the front panel of the printer to enter the passcode to access the full functionality of the front panel.
