CVE-2025-41646

Estado: AnalizadaCrítica (9.8)—

An unauthorized remote attacker can bypass the authentication of the affected software package by misusing an incorrect type conversion. This leads to full compromise of the device

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:N/PR:N/UI:N indica acceso remoto sin autenticación (T1190). Bypass de autenticación (CWE-704, type confusion) permite acceso completo: credenciales/sesión (T1078.001), ejecución de comandos y manipulación de datos en dispositivo RevPI comprometido.

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.
