CVE-2016-4338

Estado: ModificadaAlta (8.1)—💥 Exploit
La secuencia de comandos de configuración de parámetros de usuario de mysql (userparameter_mysql.conf) en el agente en Zabbix en versiones anteriores a 2.0.18, 2.2.x en versiones anteriores a 2.2.13 y 3.0.x en versiones anteriores a 3.0.3, cuando se utiliza con un shell que no sea bash, permite a atacantes dependientes de contexto ejecutar código arbitrario o comandos SQL a través del parámetro mysql.size.
CVSS

Versión: 3.0
Vector: CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
Puntuación base: 8.1
Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 21%
Percentil entre todas las CVEs puntuadas: 98
Fecha de la puntuación: 8/10/2026
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.
