CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:H
- Puntuación base: 7
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 1.30%
- Percentil entre todas las CVEs puntuadas: 70
- 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
T1190Exploit Public-Facing Applicationinitial access45 % - Impacto principal
T1499.004Application or System Exploitationimpact65 % - Impacto secundario
T1068Exploitation for Privilege Escalationprivilege escalation35 %
Vector CVSS N/AC:H sugiere red sin privilegios, pero la DoS (A:H) por doble cierre de fd en libcurl requiere condiciones precisas. El impacto primario es denegación de servicio por corrupción de recursos del sistema; secundariamente, fallo de integridad de conexiones.
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.
