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. (CVE-2015-5345)

Impact

A remote attacker may be able to determine the existence of restricted
directories by exploiting this vulnerability.

BIG-IP/Enterprise Manager

The Tomcat service is not directly exposed to the network, as it only
listens on a localhost socket with connections brokered through the
Apache front-end web service.

Traffix SDC Exploitation of this vulnerability may occur if an
attacker has access to the local network of the system; the Tomcat
service is accessible only from the internal network."
