Vulnerabilidad alta de escalado de privilegios en hMailServer 6.3.4 y 6.3.5

El servicio hmailserver-update en hMailServer 6.3.4 y 6.3.5 ejecuta operaciones como root sin validar correctamente los parámetros de actualización proporcionados por la cuenta de servicio no privilegiada, permitiendo escalado de privilegios. Un atacante con acceso a la cuenta hmailserver podría comprometer completamente el servidor de correo y la infraestructura subyacente. Esta vulnerabilidad afecta directamente a empresas LATAM que ejecutan hMailServer como solución de correo corporativo.
