Vulnerabilidad alta en hMailServer: validación de Host faltante permite ataque de fuerza bruta

Progressive Robot hMailServer versiones 6.0.0 a 6.3.5 contienen deficiencias en la validación de encabezados HTTP y falta de limitación de intentos fallidos en su API REST, permitiendo ataques de DNS rebinding para comprometer credenciales de administrador. Empresas en LATAM que utilizan este servidor de correo son vulnerables a toma de control administrativo si el listener REST está habilitado, incluso en configuraciones de loopback.
