| 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-2008-1521 | 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-2007-4318 | 1 Zyxel | 2 Zynos, Zywall 2 | 2026-04-23 | 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-2007-4319 | 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-2007-6729 | 1 Zyxel | 1 P-330w Router | 2026-04-23 | 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. | ||||

| 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 | 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-2008-1526 | 1 Zyxel | 38 P-660h-61, P-660h-61 Firmware, P-660h-63 and 35 more | 2026-04-23 | 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-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. | ||||
| 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-2008-1259 | 1 Zyxel | 1 P-2602hw-d1a | 2026-04-23 | 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-2008-1524 | 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-2007-4316 | 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 has a certain default password, which allows remote attackers to perform administrative actions. | ||||
| 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-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-2026-6058 | 1 Zyxel | 1 Wre6505 Firmware | 2026-04-22 | 4.5 Medium |
| ** 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. A malicious user may exploit numerous vectors to execute arbitrary commands on the router, such as the ping_ip parameter to the expert/maintenance/diagnostic/nslookup URI. | ||||
| CVE-2026-1459 | 1 Zyxel | 12 Dx5401-b1, Dx5401-b1 Firmware, Emg3525-t50b and 9 more | 2026-04-18 | 7.2 High |
| A post-authentication command injection vulnerability in the TR-369 certificate download CGI program of the Zyxel VMG3625-T50B firmware versions through 5.50(ABPM.9.7)C0 could allow an authenticated attacker with administrator privileges to execute operating system (OS) commands on an affected device. | ||||
| CVE-2006-2562 | 1 Zyxel | 1 P-335wt Router | 2026-04-16 | N/A |
| ZyXEL P-335WT router allows remote attackers to bypass access restrictions and conduct unauthorized operations via a UPnP request with a modified InternalClient parameter, which is not validated, as demonstrated by using AddPortMapping to forward arbitrary traffic. | ||||
| CVE-2002-0438 | 1 Zyxel | 1 Zywall10 | 2026-04-16 | N/A |
| ZyXEL ZyWALL 10 before 3.50 allows remote attackers to cause a denial of service via an ARP packet with the firewall's IP address and an incorrect MAC address, which causes the firewall to disable the LAN interface. | ||||
