Descriptions

The UniFi Video Server v3.9.3 and prior (for Windows 7/8/10 x64) web interface Firmware Update functionality, under certain circumstances, does not validate firmware download destinations to ensure they are within the intended destination directory tree. It accepts a request with a URL to firmware update information. If the version field contains ..\ character sequences, the destination file path to save the firmware can be manipulated to be outside the intended destination directory tree. Fixed in UniFi Video Controller v3.10.3 and newer.

La funcionalidad Firmware Update de la interfaz web de UniFi Video Server versiones v3.9.3 y anteriores (para Windows 7/8/10 x64), en determinadas circunstancias, no comprueba los destinos de descarga de firmware para garantizar que estén dentro del árbol de directorios de destino previsto. Acepta una petición con una URL para actualizar la información del firmware. Si el campo de versión contiene secuencias de caracteres ..\, la ruta de archivo de destino para guardar el firmware puede ser manipulada para que esté fuera del árbol de directorios de destino previsto. Corregido en UniFi Video Controller versión v3.10.3 y más recientes.
