Upgrade org.apache.tomcat:tomcat to version 8.5.94, 9.0.81 or higher.
Overview
org.apache.tomcat:tomcat is an implementation of the Java Servlet, JavaServer Pages, Java Expression Language and Java WebSocket technologies.
Affected versions of this package are vulnerable to Incomplete Cleanup in the internal fork of Commons FileUpload package. An attacker can potentially cause a denial of service on Windows by opening a stream for an uploaded file but failing to close the stream. This results in the file never being deleted from the disk, creating the possibility of an eventual denial of service due to the disk being full.
Note:
This vulnerability is exploitable on Windows operating systems.
