ZyXEL Prestige 681 ARP Request Packet Information Disclosure
Remote / Network Access
Loss of Confidentiality
Some ZyXEL Prestige devices contains a flaw that may lead to an unauthorized information disclosure. ARP requests emitted by device could contain random parts of the memory (especially parts of recent telnet sessions) , which will disclose sensitive information to an attacker able to sniff the local network resulting in a loss of confidentiality.
Currently, there are no known upgrades, patches, or workarounds available to correct this issue.
