CVE-2025-5750

Estado: AnalizadaAlta (8.8)—

WOLFBOX Level 2 EV Charger tuya_svc_devos_activate_result_parse Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of WOLFBOX Level 2 EV Charger. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the handling of the secKey, localKey, stdTimeZone and devId parameters. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-26294.

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.

Desbordamiento de búfer en parámetros de red (secKey, localKey, etc.) sin autenticación en dispositivo remoto accesible por red adyacente (AV:A). Permite ejecución arbitraria de código en el contexto del servicio.

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.

Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar código arbitrario en las instalaciones afectadas del Cargador WOLFBOX EV Nivel 2. No se requiere autenticación para explotar esta vulnerabilidad. La falla específica se encuentra en el manejo de los parámetros secKey, localKey, stdTimeZone y devId.
