"Through the use of eSCL or SNMP protocols, an attacker can retrieve the serial number of 
a printer. By applying the attack technique described in CVE-2024-51978, the default 
administrator password can be derived from the obtained serial number. Consequently, 
if the administrator password has not been changed from its default setting, there is a 
risk that an attacker could use the generated password to gain unauthorized 
control of the device.");
