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-2008-1521 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2025-04-09 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-2008-1523 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2025-04-09 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-2008-1260 1 Zyxel 1 P-2602hw-d1a 2025-04-09 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-2008-1524 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2025-04-09 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-2022-43390 1 Zyxel 78 Ax7501-b0, Ax7501-b0 Firmware, Dx3301-t0 and 75 more 2025-04-08 5.4 Medium
A command injection vulnerability in the CGI program of Zyxel NR7101 firmware prior to V1.15(ACCC.3)C0, which could allow an authenticated attacker to execute some OS commands on a vulnerable device by sending a crafted HTTP request.
CVE-2022-43393 1 Zyxel 90 Gs1350-12hp, Gs1350-12hp Firmware, Gs1350-18hp and 87 more 2025-04-08 8.2 High
An improper check for unusual or exceptional conditions in the HTTP request processing function of Zyxel GS1920-24v2 firmware prior to V4.70(ABMH.8)C0, which could allow an unauthenticated attacker to corrupt the contents of the memory and result in a denial-of-service (DoS) condition on a vulnerable device.
CVE-2020-29583 1 Zyxel 60 Atp100, Atp100 Firmware, Atp100w and 57 more 2025-04-03 9.8 Critical
Firmware version 4.60 of Zyxel USG devices contains an undocumented account (zyfwp) with an unchangeable password. The password for this account can be found in cleartext in the firmware. This account can be used by someone to login to the ssh server or web interface with admin privileges.
CVE-2022-45439 1 Zyxel 2 Ax7501-b0, Ax7501-b0 Firmware 2025-04-03 6.5 Medium
A pair of spare WiFi credentials is stored in the configuration file of the Zyxel AX7501-B0 firmware prior to V5.17(ABPC.3)C0 in cleartext. An unauthenticated attacker could use the credentials to access the WLAN service if the configuration file has been retrieved from the device by leveraging another known vulnerability.
CVE-2022-45440 1 Zyxel 2 Ax7501-b0, Ax7501-b0 Firmware 2025-04-03 4.4 Medium
A vulnerability exists in the FTP server of the Zyxel AX7501-B0 firmware prior to V5.17(ABPC.3)C0, which processes symbolic links on external storage media. A local authenticated attacker with administrator privileges could abuse this vulnerability to access the root file system by creating a symbolic link on external storage media, such as a USB flash drive, and then logging into the FTP server on a vulnerable device.
CVE-2006-2562 1 Zyxel 1 P-335wt Router 2025-04-03 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-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.
CVE-2004-0670 1 Zyxel 1 Prestige 2025-04-03 N/A
Prestige 650HW-31 running Rompager 4.7 software allows remote attackers to cause a denial of service (device reboot) via a long password.
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-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-2002-0438 1 Zyxel 1 Zywall10 2025-04-03 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-2001-1135 1 Zyxel 1 Prestige 2025-04-03 N/A
ZyXEL Prestige 642R and 642R-I routers do not filter the routers' Telnet and FTP ports on the external WAN interface from inside access, allowing someone on an internal computer to reconfigure the router, if the password is known.
CVE-2004-1789 1 Zyxel 1 Zywall10 2025-04-03 N/A
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-2002-1072 1 Zyxel 1 Prestige 2025-04-03 N/A
