CVE-2019-15132

Estado: ModificadaMedia (5.3)—

Zabbix versiones hasta 4.4.0alpha1, permite la enumeración de usuarios. Con las peticiones de inicio de sesión, es posible enumerar los nombres de usuario de la aplicación en función de la variabilidad de las respuestas del servidor (por ejemplo, los mensajes "Login name or password is incorrect" y "No permissions for system access", o solo bloqueando durante varios segundos). Esto afecta tanto al archivo api_jsonrpc.php como al archivo index.php.

CVSS

Probabilidad de explotación (EPSS)

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).
