CVE-2011-4504 2 Genmei Mori, Zyxel 2 Pseudoics, P-330w Router 2025-04-11 7.5 HIGH N/A
The UPnP IGD implementation in the Pseudo ICS UPnP software on the ZyXEL P-330W allows remote attackers to establish arbitrary port mappings by sending a UPnP AddPortMapping action in a SOAP request to the WAN interface, related to an "external forwarding" vulnerability.
CVE-2013-6786 6 Allegrosoft, Dlink, Huawei and 3 more 7 Rompager, Dsl-2640r, Dsl-2641r and 4 more 2025-04-11 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in Allegro RomPager before 4.51, as used on the ZyXEL P660HW-D1, Huawei MT882, Sitecom WL-174, TP-LINK TD-8816, and D-Link DSL-2640R and DSL-2641R, when the "forbidden author header" protection mechanism is bypassed, allows remote attackers to inject arbitrary web script or HTML by requesting a nonexistent URI in conjunction with a crafted HTTP Referer header that is not properly handled in a 404 page. NOTE: there is no CVE for a "URL redirection" issue that some sources list separately.
CVE-2008-1521 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2025-04-09 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-2007-4319 1 Zyxel 2 Zynos, Zywall 2 2025-04-09 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-2008-1522 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2025-04-09 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-2008-1528 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2025-04-09 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-2008-1524 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2025-04-09 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-2008-1261 1 Zyxel 1 P-2602hw-d1a 2025-04-09 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-2008-1529 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2025-04-09 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-2008-1260 1 Zyxel 1 P-2602hw-d1a 2025-04-09 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-2007-6729 1 Zyxel 1 P-330w Router 2025-04-09 4.3 MEDIUM 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-2008-1525 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2025-04-09 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-2007-4318 1 Zyxel 2 Zynos, Zywall 2 2025-04-09 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.
