Descriptions

It was discovered that on Windows operating systems specifically, Kibana was not validating a user supplied path, which would load .pbf files. Because of this, a malicious user could arbitrarily traverse the Kibana host to load internal files ending in the .pbf extension. Thanks to Dominic Couture for finding this vulnerability.

Se ha detectado que en los sistemas operativos Windows específicamente, Kibana no estaba comprendiendo una ruta suministrada por el usuario, que cargaría archivos .pbf. Debido a esto, un usuario malicioso podría atravesar arbitrariamente el host de Kibana para cargar archivos internos que terminaran en la extensión .pbf. Gracias a Dominic Couture por encontrar esta vulnerabilidad.
