CVE-2025-8477

Estado: AnalizadaAlta (7.4)—

Alpine iLX-507 vCard Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected Alpine iLX-507 devices. User interaction is required to exploit this vulnerability in that the target must connect to a malicious Bluetooth device.

The specific flaw exists within the parsing of vCard data. The issue results from the lack of proper validation of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-26324.

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.

AV:A+UI:R indica explotación en cliente (Bluetooth): T1203. Buffer overflow en parsing vCard permite RCE (T1059) con contexto root (T1068).

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 los dispositivos Alpine iLX-507 afectados. Para explotar esta vulnerabilidad, se requiere la interacción del usuario, ya que el objetivo debe conectarse a un dispositivo Bluetooth malicioso.

El problema se debe a la falta de una validación adecuada de los datos proporcionados por el usuario antes de copiarlos a un búfer basado en pila de longitud fija.
