Estado: AnalizadaCrítica (9.8)—

In JetBrains TeamCity before 2025.07 privilege escalation was possible due to incorrect directory permissions

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Puntuación base: 9.8

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.18%
Percentil entre todas las CVEs puntuadas: 7
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 access75 %
Impacto principalT1068 Exploitation for Privilege Escalationprivilege escalation85 %
Impacto secundarioT1222 File and Directory Permissions Modificationdefense impairment80 %

Vector CVSS AV:N (red sin privilegios) → T1190. CWE-276 (permisos incorrectos) + escalada de privilegios explícita + acceso crítico local → T1068 como impacto principal. T1222 (permisos modificables) es el mecanismo subyacente confirmado por la descripción.

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.
