CVE-2025-9357

Estado: AnalizadaAlta (7.4)—

A vulnerability was identified in Linksys RE6250, RE6300, RE6350, RE6500, RE7000 and RE9000 1.0.013.001/1.0.04.001/1.0.04.002/1.1.05.003/1.2.07.001. This affects the function langSwitchByBBS of the file /goform/langSwitchByBBS. The manipulation of the argument langSelectionOnly leads to stack-based buffer overflow. It is possible to initiate the attack remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.

CVSS

Probabilidad de explotación (EPSS)

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.

Vector AV:N/PR:L indica acceso remoto con autenticación; CWE-119/121 (buffer overflow) en firmware permite ejecución de código. PR:L descarta T1190; T1210 por red con privilegios. Impactos: ejecución de comandos (overflow típicamente) y posible escalada a root/admin en dispositivo IoT.

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.
