CVE-2007-4319 1 Zyxel 2 Zynos, Zywall 2 2018-10-15 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.
CVE-2007-4318 1 Zyxel 2 Zynos, Zywall 2 2018-10-15 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-2007-4317 1 Zyxel 2 Zynos, Zywall 2 2018-10-15 4.3 MEDIUM 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-2007-4316 1 Zyxel 2 Zynos, Zywall 2 2018-10-15 4.3 MEDIUM N/A
The management interface in ZyNOS firmware 3.62(WK.6) on the Zyxel Zywall 2 device has a certain default password, which allows remote attackers to perform administrative actions.

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-2008-1529 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2018-10-11 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-2008-1528 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2018-10-11 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-2008-1527 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2018-10-11 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-2008-1525 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2018-10-11 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-2008-1524 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2018-10-11 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-2008-1523 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2018-10-11 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.

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-2008-1521 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2018-10-11 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.
