CVE-2026-45208

Estado: AnalizadaAlta (7.8)—

A time-of-check time-of-use vulnerability in the Apex One/SEP agent could allow a local attacker to escalate privileges on affected installations.

Please note: an attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Puntuación base: 7.8

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.13%
Percentil entre todas las CVEs puntuadas: 2
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.

ExplotaciónT1068 Exploitation for Privilege Escalationprivilege escalation95 %
Impacto principalT1548 Abuse Elevation Control Mechanismprivilege escalation85 %
Impacto secundarioT1548.004 Elevated Execution with Promptprivilege escalation80 %

TOCTOU (CWE-367) con AV:L, PR:L permite escalada de privilegios. C:H I:H A:H indican control total post-explotación. Requiere ejecución previa de código de bajo privilegio.

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.
