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-2007-4317 1 Zyxel 2 Zynos, Zywall 2 2025-04-09 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-2008-1257 1 Zyxel 4 P-660hw, P-660hw D1, P-660hw D3 and 1 more 2025-04-09 N/A

CVE-2008-1527 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2025-04-09 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-2008-1254 1 Zyxel 1 P-660hw 2025-04-09 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-2008-1523 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2025-04-09 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 2025-04-09 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-2007-6730 1 Zyxel 1 P-330w Router 2025-04-09 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-2008-1525 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2025-04-09 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-2008-1255 1 Zyxel 1 P-660hw 2025-04-09 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-2008-1260 1 Zyxel 1 P-2602hw-d1a 2025-04-09 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 2025-04-09 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-2007-6729 1 Zyxel 1 P-330w Router 2025-04-09 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-2008-1528 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2025-04-09 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-2008-1256 1 Zyxel 1 P-660hw 2025-04-09 N/A
The ZyXEL P-660HW series router has "admin" as its default password, which allows remote attackers to gain administrative access.

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-2008-1529 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2025-04-09 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-2007-1586 1 Zyxel 1 Zynos 2025-04-09 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.
