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-2008-1255 1 Zyxel 1 P-660hw 2026-04-23 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-2007-4317 1 Zyxel 2 Zynos, Zywall 2 2026-04-23 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-2007-6729 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.
CVE-2008-1529 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2026-04-23 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-2008-2167 1 Zyxel 1 Zywall 100 2026-04-23 N/A
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-2008-1524 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-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-2005-1717 1 Zyxel 1 Prestige 650r-31 2026-04-16 N/A
ZyXEL Prestige 650R-31 router running ZyNOS FW v3.40(KO.1) allows remote attackers to cause a denial of service (CPU consumption and network loss) via crafted fragmented IP packets.
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.
CVE-2002-1071 1 Zyxel 1 Prestige 2026-04-16 N/A
ZyXEL Prestige 642R allows remote attackers to cause a denial of service in the Telnet, FTP, and DHCP services (crash) via a TCP packet with both the SYN and ACK flags set.
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-2001-1194 1 Zyxel 2 Prestige 1600, Prestige 681 2026-04-16 N/A
Zyxel Prestige 681 and 1600 SDSL Routers allow remote attackers to cause a denial of service via malformed packets with (1) an IP length less than actual packet size, or (2) fragmented packets whose size exceeds 64 kilobytes after reassembly.
CVE-2004-1684 1 Zyxel 2 Prestige, Zynos 2026-04-16 N/A
Zyxel P681 running ZyNOS Vt020225a contains portions of memory in an ARP request, which allows remote attackers to obtain sensitive information by sniffing the network.
