Estado: AnalizadaAlta (7.4)—

A vulnerability was found in Tenda O3V2 1.0.0.12(3880). It has been declared as critical. This vulnerability affects the function formWifiBasicSet of the file /goform/setWrlBasicInfo of the component httpd. The manipulation of the argument extChannel leads to stack-based buffer overflow. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used.

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.

Buffer overflow en firmware de enrutador (AV:N, PR:L) accesible remotamente. Permite ejecución de código remoto en el dispositivo tras autenticación.

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.
