CVE-2025-20164
Estado: AplazadaAlta (8.3)—
A vulnerability in the Cisco Industrial Ethernet Switch Device Manager (DM) of Cisco IOS Software could allow an authenticated, remote attacker to elevate privileges.
This vulnerability is due to insufficient validation of authorizations for authenticated users. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could allow the attacker to elevate privileges to privilege level 15.
To exploit this vulnerability, the attacker must have valid credentials for a user account with privilege level 5 or higher. Read-only DM users are assigned privilege level 5.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:H
- Puntuación base: 8.3
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.34%
- Percentil entre todas las CVEs puntuadas: 25
- 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.
- Explotación
T1210Exploitation of Remote Serviceslateral movement85 % - Impacto principal
