CVEID:
CVE-2015-5345
DESCRIPTION:
Apache Tomcat could allow a remote attacker to obtain sensitive information,
caused by an error when accessing a protected directory. By redirecting to
the URL, an attacker could exploit this vulnerability to determine the

CVEID:
CVE-2015-5346
DESCRIPTION:
Apache Tomcat could allow a remote attacker to hijack a valid user's session,
caused by the failure to recycle the requestedSessionSSL field when recycling
the Request object to use for a new request. By persuading a victim to visit
a specially-crafted link and log into the application, a remote attacker
could exploit this vulnerability to hijack another user's account and
possibly launch further attacks on the system.

CVEID:
CVE-2016-0714
DESCRIPTION:
Apache Tomcat could allow a remote attacker to bypass security restrictions,
caused by an error in multiple session persistence mechanisms. By placing a
malicious object into a session, an attacker could exploit this vulnerability
to bypass a security manager and possibly execute arbitrary code on the
system.
