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-2014-7278 1 Zyxel 2 Sbg3300-n, Sbg3300-n Firmware 2023-12-10 5.0 MEDIUM N/A
The login page on the ZyXEL SBG-3300 Security Gateway with firmware 1.00(AADY.4)C0 and earlier allows remote attackers to cause a denial of service (persistent web-interface outage) via JavaScript code within unspecified "welcome message" form data that is improperly handled during use for the loginMsg variable's value, a different vulnerability than CVE-2014-7277.
CVE-2013-6786 6 Allegrosoft, Dlink, Huawei and 3 more 7 Rompager, Dsl-2640r, Dsl-2641r and 4 more 2023-12-10 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-2013-3588 1 Zyxel 11 P-660h-61, P-660h-63, P-660h-67 and 8 more 2023-12-10 7.8 HIGH N/A

CVE-2011-0746 1 Zyxel 1 O2 Dsl Router Classic 2023-12-10 4.3 MEDIUM N/A
Cross-site request forgery (CSRF) vulnerability in Forms/PortForwarding_Edit_1 on the ZyXEL O2 DSL Router Classic allows remote attackers to hijack the authentication of administrators for requests that insert cross-site scripting (XSS) sequences via the PortRule_Name parameter.
CVE-2011-4504 2 Genmei Mori, Zyxel 2 Pseudoics, P-330w Router 2023-12-10 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-2008-1528 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2023-12-10 4.0 MEDIUM N/A
ZyXEL Prestige routers, including P-660, P-661, and P-662 models with firmware 3.40(AGD.2) through 3.40(AHQ.3), allow remote authenticated users to obtain authentication data by making direct HTTP requests and then reading the HTML source, as demonstrated by a request for (1) RemMagSNMP.html, which discloses SNMP communities; or (2) WLAN.html, which discloses WEP keys.
CVE-2008-1522 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2023-12-10 7.5 HIGH N/A
ZyXEL Prestige routers, including P-660 and P-661 models with firmware 3.40(AGD.2) through 3.40(AHQ.3), have (1) "user" as their default password for the "user" account and (2) "1234" as their default password for the "admin" account, which makes it easier for remote attackers to obtain access.
CVE-2007-6729 1 Zyxel 1 P-330w Router 2023-12-10 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-2008-1525 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2023-12-10 5.0 MEDIUM N/A
The default SNMP configuration on ZyXEL Prestige routers, including P-660 and P-661 models with firmware 3.40(AGD.2) through 3.40(AHQ.3), has a Trusted Host value of 0.0.0.0, which allows remote attackers to send SNMP requests from any source IP address.
CVE-2008-2167 1 Zyxel 1 Zywall 100 2023-12-10 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in ZyXEL ZyWALL 100 allows remote attackers to inject arbitrary web script or HTML via the Referer header, which is not properly handled in a 404 Error page.
CVE-2008-1524 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2023-12-10 7.5 HIGH N/A
The SNMP service on ZyXEL Prestige routers, including P-660 and P-661 models with firmware 3.40(AGD.2) through 3.40(AHQ.3), has "public" as its default community for both (1) read and (2) write operations, which allows remote attackers to perform administrative actions via SNMP, as demonstrated by reading the Dynamic DNS service password or inserting an XSS sequence into the system.sysName.0 variable, which is displayed on the System Status page.
CVE-2008-1529 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2023-12-10 5.0 MEDIUM N/A
ZyXEL Prestige routers have a minimum password length for the admin account that is too small, which makes it easier for remote attackers to guess passwords via brute force methods.
CVE-2007-6730 1 Zyxel 1 P-330w Router 2023-12-10 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-2008-1523 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2023-12-10 5.0 MEDIUM N/A
ZyXEL Prestige routers, including P-660, P-661, and P-662 models with firmware 3.40(AGD.2) through 3.40(AHQ.3), allow remote authenticated users to obtain ISP and Dynamic DNS credentials by sending a direct request for (1) WAN.html, (2) wzPPPOE.html, and (3) rpDyDNS.html, and then reading the HTML source.
CVE-2008-1521 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2023-12-10 6.5 MEDIUM N/A
ZyXEL Prestige routers, including P-660 and P-661 models with firmware 3.40(AGD.2) through 3.40(AHQ.3), allow remote authenticated users to gain privileges by accessing administrative URIs, as demonstrated by rpSysAdmin.html.
CVE-2008-1527 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2023-12-10 7.5 HIGH N/A
ZyXEL Prestige routers, including P-660, P-661, and P-662 models with firmware 3.40(PE9) and 3.40(AGD.2) through 3.40(AHQ.3), support authentication over HTTP via a hash string in the hiddenPassword field, which allows remote attackers to obtain access via a replay attack.
CVE-2008-1259 1 Zyxel 1 P-2602hw-d1a 2023-12-10 9.3 HIGH N/A
The Zyxel P-2602HW-D1A router with 3.40(AJZ.1) firmware maintains authentication state by IP address, which allows remote attackers to bypass authentication by establishing a session from a source IP address of a user who previously authenticated within the previous 5 minutes.
CVE-2007-4318 1 Zyxel 2 Zynos, Zywall 2 2023-12-10 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in Forms/General_1 in the management interface in ZyNOS firmware 3.62(WK.6) on the Zyxel Zywall 2 device allows remote authenticated administrators to inject arbitrary web script or HTML via the sysSystemName parameter.
CVE-2007-4319 1 Zyxel 2 Zynos, Zywall 2 2023-12-10 4.0 MEDIUM N/A
The management interface in ZyNOS firmware 3.62(WK.6) on the Zyxel Zywall 2 device allows remote authenticated administrators to cause a denial of service (infinite reboot loop) via invalid configuration data. NOTE: this issue might not cross privilege boundaries, and it might be resultant from CSRF; if so, then it should not be included in CVE.
