CVE-2015-6016 describes a critical vulnerability affecting several ZyXEL devices, including the P-660HW-T1 2, PMG5318-B20A, and NBG-418N, due to a hardcoded default administrator password of "1234". This allows remote attackers to gain full administrative access with low complexity and no user interaction, leading to complete compromise of confidentiality, integrity, and availability. While there is no evidence of active exploitation or public exploit code (Metasploit, Nuclei, ExploitDB), the vulnerability has garnered significant community discussion, indicating awareness and potential for future exploitation. The high CVSS score of 9.8 and FAUCET Risk Score of 94/100 underscore its severe impact.
