CVE-2016-4340
Estado: ModificadaAlta (8.8)—💥 Exploit
La característica de suplantación en Gitlab 8.7.0, 8.6.0 hasta la versión 8.6.7, 8.5.0 hasta la versión 8.5.11, 8.4.0 hasta la versión 8.4.9, 8.3.0 hasta la versión 8.3.8 y 8.2.0 hasta la versión 8.2.4 permite a usuarios remotos autenticados para "iniciar sesión" como cualquier otro usuario a través de vectores no especificados.
CVSS
- Versión: 3.0
- Vector: CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
- Puntuación base: 8.8
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 10%
- Percentil entre todas las CVEs puntuadas: 96
- Fecha de la puntuación: 9/10/2026
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).
💥 Exploits públicos
Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
