The Zyxel P-2602HW-D1A router with 3.40(AJZ.1) firmware provides different responses to admin page requests depending on whether a user is logged in, which allows remote attackers to obtain current login status by requesting an arbitrary admin URI.
CVE-2008-1260 1 Zyxel 1 P-2602hw-d1a 2018-10-11 4.3 MEDIUM N/A
Multiple cross-site request forgery (CSRF) vulnerabilities on the Zyxel P-2602HW-D1A router with 3.40(AJZ.1) firmware allow remote attackers to (1) make the admin web server available on the Internet (WAN) interface via the WWWAccessInterface parameter to Forms/RemMagWWW_1 or (2) change the IP whitelisting timeout via the StdioTimout parameter to Forms/rpSysAdmin_1.
CVE-2008-1259 1 Zyxel 1 P-2602hw-d1a 2018-10-11 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-2008-1257 1 Zyxel 4 P-660hw, P-660hw D1, P-660hw D3 and 1 more 2018-10-11 4.3 MEDIUM N/A

CVE-2008-1256 1 Zyxel 1 P-660hw 2018-10-11 10.0 HIGH N/A
The ZyXEL P-660HW series router has "admin" as its default password, which allows remote attackers to gain administrative access.
CVE-2008-1255 1 Zyxel 1 P-660hw 2018-10-11 10.0 HIGH N/A
The ZyXEL P-660HW series router maintains authentication state by IP address, which allows remote attackers to bypass authentication by establishing a session from a source IP address of a previously authenticated user.
CVE-2008-1254 1 Zyxel 1 P-660hw 2018-10-11 6.8 MEDIUM N/A
Multiple cross-site request forgery (CSRF) vulnerabilities on the ZyXEL P-660HW series router allow remote attackers to (1) change DNS servers and (2) add keywords to the "bannedlist" via unspecified vectors.
CVE-2011-0746 1 Zyxel 1 O2 Dsl Router Classic 2018-10-09 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-2017-17901 1 Zyxel 2 P-660hw, P-660hw Firmware 2018-01-17 7.8 HIGH 7.5 HIGH
ZyXEL P-660HW v3 devices allow remote attackers to cause a denial of service (CPU consumption) via a flood of IP packets with a TTL of 1.
CVE-2001-1135 1 Zyxel 1 Prestige 2017-12-19 7.5 HIGH N/A
ZyXEL Prestige 642R and 642R-I routers do not filter the routers' Telnet and FTP ports on the external WAN interface from inside access, allowing someone on an internal computer to reconfigure the router, if the password is known.
CVE-2016-10401 1 Zyxel 2 Pk5001z, Pk5001z Firmware 2017-11-03 9.0 HIGH 8.8 HIGH
ZyXEL PK5001Z devices have zyad5001 as the su password, which makes it easier for remote attackers to obtain root access if a non-root account password is known (or a non-root default account exists within an ISP's deployment of these devices).
CVE-2015-7256 1 Zyxel 50 C1000z, C1000z Firmware, Fr1000z and 47 more 2017-10-11 4.3 MEDIUM 5.9 MEDIUM
ZyXEL NWA1100-N, NWA1100-NH, NWA1121-NI, NWA1123-AC, and NWA1123-NI access points; P-660HN-51, P-663HN-51, VMG1312-B10A, VMG1312-B30A, VMG1312-B30B, VMG4380-B10A, VMG8324-B10A, VMG8924-B10A, VMG8924-B30A, and VSG1435-B101 DSL CPEs; PMG5318-B20A GPONs; SBG3300-N000, SBG3300-NB00, and SBG3500-N000 small business gateways; GS1900-8 and GS1900-24 switches; and C1000Z, Q1000, FR1000Z, and P8702N project models use non-unique X.509 certificates and SSH host keys.
CVE-2015-6018 1 Zyxel 1 Pmg5318-b20a Firmware 2017-09-15 10.0 HIGH 9.8 CRITICAL
The diagnostic-ping implementation on ZyXEL PMG5318-B20A devices with firmware before 1.00(AANC.2)C0 allows remote attackers to execute arbitrary commands via the PingIPAddr parameter.
CVE-2014-7278 1 Zyxel 2 Sbg3300-n, Sbg3300-n Firmware 2017-09-08 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.

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-2004-1789 1 Zyxel 1 Zywall10 2017-07-11 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in the web management interface in ZyWALL 10 4.07 allows remote attackers to inject arbitrary web script or HTML via the rpAuth_1 page.
