Apache Flink 1.5.1 introduced a REST handler that allows you to write an uploaded file to an arbitrary location on the local file system, through a maliciously modified HTTP HEADER. The files can be written to any location accessible by Flink 1.5.1. All users should upgrade to Flink 1.11.3 or 1.12.0 if their Flink instance(s) are exposed. The issue was fixed in commit a5264a6f41524afe8ceadf1d8ddc8c80f323ebc4 from apache/flink:master.

Apache Flink versión 1.5.1, introdujo un controlador de REST que le permite escribir un archivo cargado en una ubicación arbitraria en el sistema de archivos local, por medio de un encabezado HTTP modificado maliciosamente. Los archivos se pueden escribir en cualquier ubicación accesible de Flink versión 1.5.1. Todos los usuarios deben actualizar a Flink versión 1.11.3 o 1.12.0 si sus instancias de Flink están expuestas. El problema se corrigió en el commit a5264a6f41524afe8ceadf1d8ddc8c80f323ebc4 de apache/flink:master
