CVSS v3.1 |
| Multiple cross-site request forgery (CSRF) vulnerabilities in the web management interface in the ZyXEL P-330W router allow remote attackers to hijack the authentication of administrators for requests that (1) enable remote router management via goform/formRmtMgt or (2) modify the administrator password via goform/formPasswordSetup. |
| 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. |
| 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. |
| The ZyXEL P-660HW series router has "admin" as its default password, which allows remote attackers to gain administrative access. |
| Cross-site scripting (XSS) vulnerability in Forms/DiagGeneral_2 on the ZyXEL P-660HW series router allows remote attackers to inject arbitrary web script or HTML via the PingIPAddr parameter. |
| 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. |
| 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. |
| ** 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| ZyXel P2000W VoIP 802.11b Wireless Phone running firmware WV.00.02 allows remote attackers to obtain sensitive information, such as MAC address and software version, by directly accessing UDP port 9090. |
| Prestige 650HW-31 running Rompager 4.7 software allows remote attackers to cause a denial of service (device reboot) via a long password. |
| 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. |
| 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. |
