Remote Access Vulnerability in ZyXEL Devices with Default Credentials

CVE-2015-6016

Summary

ZyXEL devices including the P-660HW-T1, PMG5318-B20A, and NBG-418N have a significant security flaw due to a default administrative password set to '1234'. This allows remote attackers to gain unauthorized access to the devices, potentially leading to various malicious activities. The vulnerability arises from improper authentication mechanisms that fail to enforce more secure access controls, leaving systems exposed to exploitation if left unaddressed.
