CVE-2025-40761

Estado: AplazadaAlta (8.6)—

A vulnerability has been identified in RUGGEDCOM ROX MX5000 (All versions), RUGGEDCOM ROX MX5000RE (All versions), RUGGEDCOM ROX RX1400 (All versions), RUGGEDCOM ROX RX1500 (All versions), RUGGEDCOM ROX RX1501 (All versions), RUGGEDCOM ROX RX1510 (All versions), RUGGEDCOM ROX RX1511 (All versions), RUGGEDCOM ROX RX1512 (All versions), RUGGEDCOM ROX RX1524 (All versions), RUGGEDCOM ROX RX1536 (All versions), RUGGEDCOM ROX RX5000 (All versions). Affected devices do not properly limit access through its Built-In-Self-Test (BIST) mode. This could allow an attacker with physical access to the serial interface to bypass authentication and get access to a root shell on the device.

CVSS

Versión: 4.0
Vector: CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X
Puntuación base: 8.6

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.24%
Percentil entre todas las CVEs puntuadas: 13
Fecha de la puntuación: 6/10/2026

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.

ExplotaciónT1091 Replication Through Removable Medialateral movement · initial access95 %
Impacto principalT1078 Valid Accountsstealth · persistence · privilege escalation · initial access90 %
Impacto secundarioT1068 Exploitation for Privilege Escalationprivilege escalation85 %

Acceso físico a interfaz serie (AV:P) permite eludir autenticación y obtener acceso root; requiere T1091 (medios extraíbles/acceso físico) y resulta en T1078 (acceso con credenciales) y T1068 (escalada a root).

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.
