CVE-2005-3725 1 Zyxel 1 Prestige 2000w V.1voip Wi-fi Phone 2016-10-17 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.
CVE-2014-4162 1 Zyxel 1 P-660hw 2014-07-16 6.8 MEDIUM N/A
Multiple cross-site request forgery (CSRF) vulnerabilities in the Zyxel P-660HW-T1 (v3) wireless router allow remote attackers to hijack the authentication of administrators for requests that change the (1) wifi password or (2) SSID via a request to Forms/WLAN_General_1.
CVE-2014-0355 1 Zyxel 2 N300 Netusb Nbg-419n, N300 Netusb Nbg-419n Firmware 2014-04-15 7.9 HIGH N/A
Multiple stack-based buffer overflows on the ZyXEL Wireless N300 NetUSB NBG-419N router with firmware 1.00(BFQ.6)C0 allow man-in-the-middle attackers to execute arbitrary code via (1) a long temp attribute in a yweather:condition element in a forecastrss file that is processed by the checkWeather function; the (2) WeatherCity or (3) WeatherDegree variable to the detectWeather function; unspecified input to the (4) UpnpAddRunRLQoS, (5) UpnpDeleteRunRLQoS, or (6) UpnpDeletePortCheckType function; or (7) the SET COUNTRY udps command.
CVE-2014-0354 1 Zyxel 2 N300 Netusb Nbg-419n, N300 Netusb Nbg-419n Firmware 2014-04-15 7.8 HIGH N/A
The ZyXEL Wireless N300 NetUSB NBG-419N router with firmware 1.00(BFQ.6)C0 has a hardcoded password of qweasdzxc for an unspecified account, which allows remote attackers to obtain index.asp login access via an HTTP request.
CVE-2014-0356 1 Zyxel 2 N300 Netusb Nbg-419n, N300 Netusb Nbg-419n Firmware 2014-04-15 7.9 HIGH N/A
The ZyXEL Wireless N300 NetUSB NBG-419N router with firmware 1.00(BFQ.6)C0 allows remote attackers to execute arbitrary code via shell metacharacters in input to the (1) detectWeather, (2) set_language, (3) SystemCommand, or (4) NTPSyncWithHost function in management.c, or a (5) SET COUNTRY, (6) SET WLAN SSID, (7) SET WLAN CHANNEL, (8) SET WLAN STATUS, or (9) SET WLAN COUNTRY udps command.
CVE-2014-0353 1 Zyxel 2 N300 Netusb Nbg-419n, N300 Netusb Nbg-419n Firmware 2014-04-15 6.1 MEDIUM N/A
The ZyXEL Wireless N300 NetUSB NBG-419N router with firmware 1.00(BFQ.6)C0 allows remote attackers to bypass authentication by using %2F sequences in place of / (slash) characters.
CVE-2013-3588 1 Zyxel 11 P-660h-61, P-660h-63, P-660h-67 and 8 more 2014-04-02 7.8 HIGH N/A
The web management interface on Zyxel P660 devices allows remote attackers to cause a denial of service (reboot) via a flood of TCP SYN packets.
CVE-2013-6786 6 Allegrosoft, D-link, Huawei and 3 more 7 Rompager, Dsl-2640r, Dsl-2641r and 4 more 2014-01-17 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in Allegro RomPager before 4.51, as used on the ZyXEL P660HW-D1, Huawei MT882, Sitecom WL-174, TP-LINK TD-8816, and D-Link DSL-2640R and DSL-2641R, when the "forbidden author header" protection mechanism is bypassed, allows remote attackers to inject arbitrary web script or HTML by requesting a nonexistent URI in conjunction with a crafted HTTP Referer header that is not properly handled in a 404 page. NOTE: there is no CVE for a "URL redirection" issue that some sources list separately.
CVE-2011-4504 2 Genmei Mori, Zyxel 2 Pseudoics, P-330w Router 2012-03-07 7.5 HIGH N/A
The UPnP IGD implementation in the Pseudo ICS UPnP software on the ZyXEL P-330W allows remote attackers to establish arbitrary port mappings by sending a UPnP AddPortMapping action in a SOAP request to the WAN interface, related to an "external forwarding" vulnerability.
CVE-2007-6730 1 Zyxel 1 P-330w Router 2009-09-14 9.3 HIGH N/A
Multiple cross-site request forgery (CSRF) vulnerabilities in the web management interface in the ZyXEL P-330W router allow remote attackers to hijack the authentication of administrators for requests that (1) enable remote router management via goform/formRmtMgt or (2) modify the administrator password via goform/formPasswordSetup.
CVE-2007-6729 1 Zyxel 1 P-330w Router 2009-09-14 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in the web management interface in the ZyXEL P-330W router allows remote attackers to inject arbitrary web script or HTML via the pingstr parameter and other unspecified vectors.
CVE-2005-1717 1 Zyxel 1 Prestige 650r-31 2008-09-05 5.0 MEDIUM N/A
ZyXEL Prestige 650R-31 router running ZyNOS FW v3.40(KO.1) allows remote attackers to cause a denial of service (CPU consumption and network loss) via crafted fragmented IP packets.
CVE-2002-1071 1 Zyxel 1 Prestige 2008-09-05 5.0 MEDIUM N/A
ZyXEL Prestige 642R allows remote attackers to cause a denial of service in the Telnet, FTP, and DHCP services (crash) via a TCP packet with both the SYN and ACK flags set.
CVE-2002-1072 1 Zyxel 1 Prestige 2008-09-05 5.0 MEDIUM N/A
ZyXEL Prestige 642R 2.50(FA.1) and Prestige 310 V3.25(M.01), allows remote attackers to cause a denial of service via an oversized, fragmented "jolt" style ICMP packet.
