Descriptions

Wowza Streaming Engine through 4.8.11+5 could allow an authenticated, remote attacker to exhaust filesystem resources via the /enginemanager/server/vhost/historical.jsdata vhost parameter. This is due to the insufficient management of available filesystem resources. An attacker could exploit this vulnerability through the Virtual Host Monitoring section by requesting random virtual-host historical data and exhausting available filesystem resources. A successful exploit could allow the attacker to cause database errors and cause the device to become unresponsive to web-based management. (Manual intervention is required to free filesystem resources and return the application to an operational state.)

Wowza Streaming Engine versiones hasta 4.8.11+5, podría permitir a un atacante remoto autenticado agotar los recursos del sistema de archivos por medio del parámetro vhost /enginemanager/server/vhost/historical.jsdata. Esto es debido a una administración insuficiente de los recursos disponibles del sistema de archivos. Un atacante podría explotar esta vulnerabilidad mediante la sección de monitorización de hosts virtuales al solicitar datos históricos de hosts virtuales al azar y agotando los recursos disponibles del sistema de archivos. Una explotación con éxito podría permitir al atacante causar errores en la base de datos y causar que el dispositivo no responda a la administración basada en la web. (Es requerida la intervención manual para liberar los recursos del sistema de archivos y devolver la aplicación a un estado operativo)
