CVE-2005-0328 2 Netgear, Zyxel 3 Rt311, Rt314, Prestige 2025-04-03 5.0 MEDIUM N/A
Zyxel P310, P314, P324 and Netgear RT311, RT314 running the latest firmware, allows remote attackers on the WAN to obtain the IP address of the LAN side interface by pinging a valid LAN IP address, which generates an ARP reply from the WAN address side that maps the LAN IP address to the WAN's MAC address.
CVE-2005-3725 1 Zyxel 1 Prestige 2000w V.1voip Wi-fi Phone 2025-04-03 6.4 MEDIUM N/A
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.
