CVSS v3.1 |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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 default SNMP configuration on ZyXEL Prestige routers, including P-660 and P-661 models with firmware 3.40(AGD.2) through 3.40(AHQ.3), has a Trusted Host value of 0.0.0.0, which allows remote attackers to send SNMP requests from any source IP address. |
| 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. |
| 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. |
| 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. |
| ZyXEL ZyWALL 1050 has a hard-coded password for the Quagga and Zebra processes that is not changed when it is set by a user, which allows remote attackers to gain privileges. |
| 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. |
| 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, 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. |
| ** 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 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. |
| Prestige 650HW-31 running Rompager 4.7 software allows remote attackers to cause a denial of service (device reboot) via a long password. |
