| Cross-site scripting (XSS) vulnerability in the web management interface in ZyWALL 10 4.07 allows remote attackers to inject arbitrary web script or HTML via the rpAuth_1 page. | ||||
| CVE-2004-1540 | 1 Zyxel | 2 Prestige, Zynos | 2025-04-03 | N/A |
| ZyXEL Prestige 623, 650, and 652 HW Routers, and possibly other versions, with HTTP Remote Administration enabled, does not require a password to access rpFWUpload.html, which allows remote attackers to reset the router configuration file. | ||||
| CVE-2005-3724 | 1 Zyxel | 2 P2000w Version 1 Voip Wifi Phone, Prestige 2000w V.1voip Wi-fi Phone | 2025-04-03 | N/A |
| Zyxel P2000W Version 1 VOIP WIFI Phone Wj.00.10 allows remote attackers to obtain sensitive information and possibly cause a denial of service via a direct connection to UDP port 9090, which is undocumented and does not require authentication. | ||||
| CVE-2002-1072 | 1 Zyxel | 1 Prestige | 2025-04-03 | N/A |
| ZyXEL Prestige 642R 2.50(FA.1) and Prestige 310 V3.25(M.01), allows remote attackers to cause a denial of service via an oversized, fragmented "jolt" style ICMP packet. | ||||
| CVE-2005-0328 | 2 Netgear, Zyxel | 3 Rt311, Rt314, Prestige | 2025-04-03 | N/A |
| Zyxel P310, P314, P324 and Netgear RT311, RT314 running the latest firmware, allows remote attackers on the WAN to obtain the IP address of the LAN side interface by pinging a valid LAN IP address, which generates an ARP reply from the WAN address side that maps the LAN IP address to the WAN's MAC address. | ||||
| CVE-2005-3725 | 1 Zyxel | 1 Prestige 2000w V.1voip Wi-fi Phone | 2025-04-03 | N/A |
| Zyxel P2000W Version 1 VOIP WIFI Phone Wj.00.10 uses hardcoded IP addresses for its DNS servers, which could allow remote attackers to cause a denial of service or hijack Zyxel phones by attacking or spoofing the hardcoded DNS servers. NOTE: it could be argued that this issue reflects an inherent limitation of DNS itself, so perhaps it should not be included in CVE. | ||||

| 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-2006-3929 | 1 Zyxel | 1 Prestige 660h-61 | 2025-04-03 | N/A |
| Cross-site scripting (XSS) vulnerability in the Forms/rpSysAdmin script on the Zyxel Prestige 660H-61 ADSL Router running firmware 3.40(PT.0)b32 allows remote attackers to inject arbitrary web script or HTML via hex-encoded values in the a parameter. | ||||
| CVE-2004-1684 | 1 Zyxel | 2 Prestige, Zynos | 2025-04-03 | 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. | ||||
| CVE-2002-1071 | 1 Zyxel | 1 Prestige | 2025-04-03 | 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-2020-9054 | 1 Zyxel | 54 Atp100, Atp100 Firmware, Atp200 and 51 more | 2025-03-21 | 9.8 Critical |
| Multiple ZyXEL network-attached storage (NAS) devices running firmware version 5.21 contain a pre-authentication command injection vulnerability, which may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable device. ZyXEL NAS devices achieve authentication by using the weblogin.cgi CGI executable. This program fails to properly sanitize the username parameter that is passed to it. If the username parameter contains certain characters, it can allow command injection with the privileges of the web server that runs on the ZyXEL device. Although the web server does not run as the root user, ZyXEL devices include a setuid utility that can be leveraged to run any command with root privileges. As such, it should be assumed that exploitation of this vulnerability can lead to remote code execution with root privileges. By sending a specially-crafted HTTP POST or GET request to a vulnerable ZyXEL device, a remote, unauthenticated attacker may be able to execute arbitrary code on the device. This may happen by directly connecting to a device if it is directly exposed to an attacker. However, there are ways to trigger such crafted requests even if an attacker does not have direct connectivity to a vulnerable devices. For example, simply visiting a website can result in the compromise of any ZyXEL device that is reachable from the client system. Affected products include: NAS326 before firmware V5.21(AAZF.7)C0 NAS520 before firmware V5.21(AASZ.3)C0 NAS540 before firmware V5.21(AATB.4)C0 NAS542 before firmware V5.21(ABAG.4)C0 ZyXEL has made firmware updates available for NAS326, NAS520, NAS540, and NAS542 devices. Affected models that are end-of-support: NSA210, NSA220, NSA220+, NSA221, NSA310, NSA310S, NSA320, NSA320S, NSA325 and NSA325v2 | ||||
| CVE-2023-27992 | 1 Zyxel | 6 Nas326, Nas326 Firmware, Nas540 and 3 more | 2025-03-19 | 9.8 Critical |
| The pre-authentication command injection vulnerability in the Zyxel NAS326 firmware versions prior to V5.21(AAZF.14)C0, NAS540 firmware versions prior to V5.21(AATB.11)C0, and NAS542 firmware versions prior to V5.21(ABAG.11)C0 could allow an unauthenticated attacker to execute some operating system (OS) commands remotely by sending a crafted HTTP request. | ||||
