CVE-2025-8320

Estado: AnalizadaAlta (8.8)—

Tesla Wall Connector Content-Length Header Improper Input Validation Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Tesla Wall Connector devices. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the parsing of the HTTP Content-Length header. The issue results from the lack of proper validation of user-supplied data, which can result in memory access past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-26300.

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.

Ataque de red adyacente (AV:A) sin autenticación contra servicio remoto (Wall Connector), buffer overflow en Content-Length permite RCE. Potencial DoS por corrupción de memoria.

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 de dispositivos Tesla Wall Connector.
