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 2024-11-21 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 2024-11-21 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 2024-11-21 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-2008-1526 1 Zyxel 38 P-660h-61, P-660h-61 Firmware, P-660h-63 and 35 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
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), do not use a salt when calculating an MD5 password hash, which makes it easier for attackers to crack passwords.
CVE-2008-1525 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2024-11-21 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 2024-11-21 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 2024-11-21 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-2008-1522 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2024-11-21 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-2008-1521 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2024-11-21 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-2008-1261 1 Zyxel 1 P-2602hw-d1a 2024-11-21 5.0 MEDIUM 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-2008-1260 1 Zyxel 1 P-2602hw-d1a 2024-11-21 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 2024-11-21 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 2024-11-21 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in Forms/DiagGeneral_2 on the ZyXEL P-660HW series router allows remote attackers to inject arbitrary web script or HTML via the PingIPAddr parameter.
CVE-2008-1256 1 Zyxel 1 P-660hw 2024-11-21 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 2024-11-21 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 2024-11-21 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-2008-1160 1 Zyxel 2 Zywall 1050, Zywall 1050 Firmware 2024-11-21 7.5 HIGH 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-2007-4319 1 Zyxel 2 Zynos, Zywall 2 2024-11-21 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 2024-11-21 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.
