CVE-2025-65883

Estado: AnalizadaAlta (8.4)—

A vulnerability has been identified in Genexis Platinum P4410 router (Firmware P4410-V2–1.41) that allows a local network attacker to achieve Remote Code Execution (RCE) with root privileges. The issue occurs due to improper session invalidation after administrator logout. When an administrator logs out, the session token remains valid. An attacker on the local network can reuse this stale token to send crafted requests via the router’s diagnostic endpoint, resulting in command execution as root.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Puntuación base: 8.4

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.38%
Percentil entre todas las CVEs puntuadas: 29
Fecha de la puntuación: 5/10/2026

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.
