CVE-2005-3725: Zyxel Prestige 2000w v.1voip Wi-Fi Phone

Medium severity, CVSS 6.4. EPSS: 1.2% chance of exploitation in the next 30 days.

Zyxel P2000W Version 1 VOIP WIFI Phone Wj.00.10 uses hardcoded IP addresses for its DNS servers, which could allow remote attackers to cause a denial of service or hijack Zyxel phones by attacking or spoofing the hardcoded DNS servers. NOTE: it could be argued that this issue reflects an inherent limitation of DNS itself, so perhaps it should not be included in CVE.
