CVE-2015-5345

The Mapper component in Apache Tomcat 6.x before 6.0.45, 7.x before 7.0.68, 8.x before 8.0.30, and 9.x before 9.0.0.M2 processes redirects before considering security constraints and Filters, which allows remote attackers to determine the existence of a directory via a URL that lacks a trailing / (slash) character.

From the Ubuntu Security Team

It was discovered that the Tomcat mapper component incorrectly handled redirects. A remote attacker could use this issue to determine the existence of a directory.
