CVE-2026-20190

Estado: AnalizadaAlta (7.5)—

A vulnerability in Cisco ISE and ISE-PIC could allow an unauthenticated, remote attacker to view sensitive information on an affected device.

This vulnerability is due to improper authorization checks when a resource is accessed. An attacker could exploit this vulnerability by sending crafted traffic to an affected device. A successful exploit could allow the attacker to gain access to sensitive information, including hashed credentials that could be used in future attacks.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Puntuación base: 7.5

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.50%
Percentil entre todas las CVEs puntuadas: 41
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.

ExplotaciónT1190 Exploit Public-Facing Applicationinitial access95 %
Impacto principalT1552.007 Container APIcredential access85 %
Impacto secundarioT1212 Exploitation for Credential Accesscredential access75 %

Vector CVSS AV:N/PR:N/UI:N indica aplicación expuesta en red sin autenticación (T1190). El atacante obtiene credenciales hasheadas y datos sensibles (T1552.007: credenciales almacenadas), útiles para ataques posteriores (T1212).

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.
