Description

It was discovered that Tomcat did not correctly validate WAR filenames or paths when deploying. A remote attacker could send a specially crafted WAR file to be deployed and cause arbitrary files and directories to be created, overwritten, or deleted.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
