CVE-2025-29387

Estado: AnalizadaAlta (7.1)—

In Tenda AC9 v1.0 V15.03.05.14_multi, the wanSpeed parameter of /goform/AdvSetMacMtuWan has a stack overflow vulnerability, which can lead to remote arbitrary code execution.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H
Puntuación base: 7.1

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.56%
Percentil entre todas las CVEs puntuadas: 45
Fecha de la puntuación: 5/10/2026

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

ExplotaciónT1203 Exploitation for Client Executionexecution85 %
Impacto principalT1059 Command and Scripting Interpreterexecution85 %
Impacto secundarioT1068 Exploitation for Privilege Escalationprivilege escalation70 %

Requiere interacción del usuario (UI:R) en acceso de red autenticado (PR:L), típico de explotación en cliente. Stack overflow remoto en firmware permite ejecución de código arbitrario y potencial escalada de privilegios.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
