CVE-2008-1160 1 Zyxel 2 Zywall 1050, Zywall 1050 Firmware 2026-04-23 9.8 Critical
ZyXEL ZyWALL 1050 has a hard-coded password for the Quagga and Zebra processes that is not changed when it is set by a user, which allows remote attackers to gain privileges.
CVE-2008-1522 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2026-04-23 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-2007-4319 1 Zyxel 2 Zynos, Zywall 2 2026-04-23 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.
CVE-2008-1523 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2026-04-23 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-2007-6730 1 Zyxel 1 P-330w Router 2026-04-23 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-2008-1528 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2026-04-23 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-2008-1255 1 Zyxel 1 P-660hw 2026-04-23 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-2008-1521 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2026-04-23 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-2007-4317 1 Zyxel 2 Zynos, Zywall 2 2026-04-23 N/A
Multiple cross-site request forgery (CSRF) vulnerabilities in the management interface in ZyNOS firmware 3.62(WK.6) on the Zyxel Zywall 2 device allow remote attackers to perform certain actions as administrators, as demonstrated by a request to Forms/General_1 with the (1) sysSystemName and (2) sysDomainName parameters.
CVE-2008-1524 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2026-04-23 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-2008-1260 1 Zyxel 1 P-2602hw-d1a 2026-04-23 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-2008-1261 1 Zyxel 1 P-2602hw-d1a 2026-04-23 N/A
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-2007-1586 1 Zyxel 1 Zynos 2026-04-23 N/A
ZynOS 3.40 allows remote attackers to cause a denial of service (link restart) by sending a request for the name \M via the SMB Mail Slot Protocol.

** UNSUPPORTED WHEN ASSIGNED ** An improper encoding or escaping vulnerability in the CGI program of Zyxel WRE6505 v2 firmware version V1.00(ABDV.3)C0 could allow an adjacent attacker on the WLAN to cause a denial-of-service (DoS) condition in the web management interface by convincing an authenticated administrator to visit the “AP Select” page while a malformed SSID is present.
CVE-2017-6884 1 Zyxel 2 Emg2926, Emg2926 Firmware 2026-04-21 8.8 High
A command injection vulnerability was discovered on the Zyxel EMG2926 home router with firmware V1.00(AAQT.4)b8. The vulnerability is located in the diagnostic tools, specifically the nslookup function.
