CVSS v3.1 |
| A post-authentication command injection vulnerability in the “DomainName” parameter of the DHCP configuration file in Zyxel DX3301-T0 and EX3301-T0 firmware versions through 5.50(ABVY.7.1)C0 could allow an authenticated attacker with administrator privileges to execute OS commands on an affected device. |
| A stack-based buffer overflow vulnerability in the CGI program of Zyxel GS1900-48HPv2 firmware versions through 2.90(ABTQ.1)C0 could allow a LAN-based, unauthenticated attacker to exploit the flaw and potentially execute OS commands via a crafted HTTP request. |
| ** UNSUPPORTED WHEN ASSIGNED ** A command injection vulnerability in the CGI program of Zyxel WRE6505 v2 firmware version V1.00(ABDV.3)C0 could allow an adjacent attacker on the LAN to execute operating system (OS) commands on a vulnerable device by sending a crafted HTTP request. |
| A buffer overflow vulnerability in the UPnP AddPortMapping() command in Zyxel VMG4005-B50B firmware versions through 5.13(ABRL.5.4)C0 could allow an adjacent attacker to trigger a temporary denial-of-service (DoS) condition affecting the UPnP function of the affected device. |
| A buffer overflow vulnerability in the UPnP DeletePortMapping() command in Zyxel VMG4005-B50B firmware versions through 5.13(ABRL.5.4)C0 could allow an adjacent attacker to trigger a temporary denial-of-service (DoS) condition affecting the UPnP function of the affected device. |
| A missing authorization vulnerability in Zyxel GS1200-5v3 firmware versions through 1.00(ACPS.2)C0, GS1200-8v3 firmware versions through 1.00(ACPT.2)C0, GS1200-5HPv3 firmware versions through 1.00(ACPU.2)C0, GS1200-8HPv3 firmware versions through 1.00(ACPV.2)C0, and GS1200-10v3 firmware versions through 1.00(ACPW.2)C0 could allow a LAN-based, unauthenticated attacker to read the system configuration from a log file via a crafted HTTP request. |
| ** UNSUPPORTED WHEN ASSIGNED ** An insecure storage of sensitive information vulnerability in the configuration file of Zyxel WRE6505 v2 firmware version V1.00(ABDV.3)C0 could allow a local attacker with administrator privileges to download and decrypt a backup configuration file. |
| ** UNSUPPORTED WHEN ASSIGNED ** A buffer overflow vulnerability in the formWep(), formWlAc(), formPasswordSetup(), formUpgradeCert(), and formDelcert() functions of the “webs” binary in Zyxel NWA1100-N customized firmware version 1.00(AACE.1)C0 could allow an attacker to trigger a denial-of-service (DoS) condition by sending a crafted HTTP request to a vulnerable device. |
| ** UNSUPPORTED WHEN ASSIGNED ** An improper restriction of excessive authentication attempts vulnerability in the web management interface of Zyxel WRE6505 v2 firmware version V1.00(ABDV.3)C0 could allow an adjacent attacker on the LAN to brute-force the password and bypass authentication. |
| A post-authentication command injection vulnerability in the EasyMesh-related APIs of Zyxel DX3300-T0 firmware versions through 5.50(ABVY.7.1)C0 could allow an authenticated, adjacent attacker with administrator privileges to execute OS commands on an affected device. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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-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. |
| 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. |
| 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. |
| 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. |
