CVE-2025-49739

Estado: AnalizadaAlta (8.8)—

Improper link resolution before file access ('link following') in Visual Studio allows an unauthorized attacker to elevate privileges over a network.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Puntuación base: 8.8

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.87%
Percentil entre todas las CVEs puntuadas: 58
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.

ExplotaciónT1203 Exploitation for Client Executionexecution85 %
Impacto principalT1068 Exploitation for Privilege Escalationprivilege escalation80 %

UI:R indica interacción del usuario (abrir proyecto malicioso); AV:N/AC:L permite explotación remota. Link following (CWE-59) combinado con privilegios elevados genera escalada post-explotación.

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.
