## Description

The org.apache.catalina.connector.Response.encodeURL method in Red Hat
JBoss Web 7.1.x and earlier, when the tracking mode is set to COOKIE, sends
the jsessionid in the URL of the first response of a session, which allows
remote attackers to obtain the session id (1) via a man-in-the-middle
attack or (2) by reading a log.
