Top Risky CVEs
| CVE | Summary | Severity | CVSS | EPSS | Priority | Signals |
|---|---|---|---|---|---|---|
| CVE-2024-40891 | Zyxel VMG4325-B10A legacy DSL CPE contains post-authentication command injection via Telnet management commands, companion vulnerability to CVE-2024-40890 affecting the same unsupported device. | HIGH | 8.8 | 55.4% | 149 |
KEV
No patch
|
| CVE-2025-0890 | **UNSUPPORTED WHEN ASSIGNED** Insecure default credentials for the Telnet function in the legacy DSL CPE Zyxel VMG4325-B10A firmware version 1.00(AAFR.4)C0_20170615 could allow an attacker to log in. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Epss exploitation probability 23.8% and no vendor patch available. | CRITICAL | 9.8 | 23.8% | 73 |
No patch
|
| CVE-2025-1731 | An incorrect permission assignment vulnerability in the PostgreSQL commands of the Zyxel USG FLEX H series uOS firmware versions from V1.20 through V1.31 could allow an authenticated local attacker. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. Public exploit code available and no vendor patch available. | HIGH | 7.8 | 0.1% | 59 |
PoC
No patch
|
| CVE-2025-13942 | Command injection in Zyxel EX3510-B0 router UPnP functionality via firmware versions through 5.17. Allows remote code execution through the UPnP service. | CRITICAL | 9.8 | 0.5% | 49 |
No patch
|
| CVE-2025-3577 | **UNSUPPORTED WHEN ASSIGNED** A path traversal vulnerability in the web management interface of the Zyxel AMG1302-T10B firmware version 2.00(AAJC.16)C0 could allow an authenticated attacker with. Rated medium severity (CVSS 4.9), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available. | MEDIUM | 4.9 | 2.8% | 47 |
PoC
No patch
|
| CVE-2026-7256 | Command injection in Zyxel WRE6505 v2 firmware V1.00(ABDV.3)C0 allows unauthenticated adjacent network attackers to execute arbitrary operating system commands via crafted HTTP requests to the CGI interface. This vulnerability affects an end-of-life product with no vendor support, meaning no security patches will be released. Exploitation requires adjacent network access (same LAN segment) but no authentication, making it exploitable by any device on the local network including compromised IoT devices or malicious insiders. | HIGH | 8.8 | 0.8% | 45 |
No patch
|
| CVE-2025-13943 | A post-authentication command injection vulnerability in the log file download function of the Zyxel EX3301-T0 firmware versions through 5.50(ABVY.7)C0 could allow an authenticated attacker to execute operating system (OS) commands on an affected device. [CVSS 8.8 HIGH] | HIGH | 8.8 | 0.2% | 44 |
No patch
|
| CVE-2026-7287 | Remote unauthenticated attackers can crash Zyxel NWA1100-N access points running customized firmware version 1.00(AACE.1)C0 by sending malformed HTTP requests that trigger buffer overflows in five distinct web server functions (formWep, formWlAc, formPasswordSetup, formUpgradeCert, formDelcert). The vulnerability enables denial-of-service attacks with high CVSS 7.5 severity but is limited to an end-of-life product according to Zyxel's reference documentation. No public exploit code identified at time of analysis, and EPSS data is unavailable for this recent CVE. | HIGH | 7.5 | 0.3% | 38 |
No patch
|
| CVE-2024-11253 | A post-authentication command injection vulnerability in the "DNSServer” parameter of the diagnostic function in the Zyxel VMG8825-T50K firmware version V5.50(ABOM.8.5)C0 and earlier could allow an authenticated attacker with administrator privileges to execute operating system (OS) commands on a vulnerable device. [CVSS 7.2 HIGH] | HIGH | 7.2 | 0.3% | 36 |
No patch
|
| CVE-2024-12009 | A post-authentication command injection vulnerability in the "ZyEE" function of the Zyxel EX5601-T1 firmware version V5.70(ACDZ.3.6)C0 and earlier could allow an authenticated attacker with administrator privileges to execute operating system (OS) commands on a vulnerable device. [CVSS 7.2 HIGH] | HIGH | 7.2 | 0.3% | 36 |
No patch
|
| CVE-2024-12010 | A post-authentication command injection vulnerability in the ”zyUtilMailSend” function of the Zyxel AX7501-B1 firmware version V5.17(ABPC.5.3)C0 and earlier could allow an authenticated attacker with administrator privileges to execute operating system (OS) commands on a vulnerable device. [CVSS 7.2 HIGH] | HIGH | 7.2 | 0.3% | 36 |
No patch
|
| CVE-2025-11730 | A post‑authentication command injection vulnerability in the Dynamic DNS (DDNS) configuration CLI command in Zyxel ATP series firmware versions from V5.35 through V5.41, USG FLEX series firmware versions from V5.35 through V5.41, USG FLEX 50(W) series firmware versions from V5.35 through V5.41, and USG20(W)-VPN series firmware versions from V5.35 through V5.41 could allow an authenticated attacker with administrator privileges to execute operating system (OS) commands on an affected device by supplying a specially crafted string as an argument to the CLI command. [CVSS 7.2 HIGH] | HIGH | 7.2 | 0.3% | 36 |
No patch
|
| CVE-2026-1460 | Command injection in Zyxel DX3301-T0 and EX3301-T0 routers allows authenticated administrators to execute arbitrary OS commands by injecting malicious input into the DomainName parameter of DHCP configuration. Affects firmware versions through 5.50(ABVY.7.1)C0. Vendor Zyxel has published a security advisory with remediation guidance. EPSS data not available; no public exploit identified at time of analysis. While CVSS score is 7.2 (High), practical risk is constrained by requirement for admin-level authentication, limiting exposure to credential compromise or malicious insider scenarios. | HIGH | 7.2 | 0.2% | 36 |
No patch
|
| CVE-2026-1459 | Zyxel VMG3625-T50B, DX5401 B1, and EMG5523 T50B devices with firmware through version 5.50(ABPM.9.7)C0 contain a post-authentication command injection vulnerability in the TR-369 certificate download function that allows authenticated administrators to execute arbitrary operating system commands. An attacker with admin credentials could leverage this to gain complete control over the affected device. No patch is currently available. | HIGH | 7.2 | 0.1% | 36 |
No patch
|
| CVE-2026-0711 | Command injection in EasyMesh APIs of Zyxel DX3300-T0 firmware through version 5.50(ABVY.7.1)C0 allows authenticated administrators with adjacent network access to execute arbitrary OS commands on the device. The vulnerability requires both administrator privileges and adjacent network positioning (AV:A), significantly limiting exposure to local network attackers rather than remote threat actors. CVSS 6.8 reflects high confidentiality, integrity, and availability impact but is constrained by elevated privilege and adjacency requirements. | MEDIUM | 6.8 | 0.2% | 34 |
