"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.

This plugin only works with Tenable.ot.

"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. 

For more information about the protected mode and to apply it to Zebra printer products 
that may be affected, see the Link-OS Printer Administration Guide.");
