Apache Tomcat 8.0.0.RC1 < 8.0.32 Multiple Vulnerabilities

Synopsis :

The remote Apache Tomcat server is affected by multiple
vulnerabilities.

Description :

According to its self-reported version number, the Apache Tomcat
service running on the remote host is 8.0.x prior to 8.0.32. It is,
therefore, affected by multiple vulnerabilities :

- A flaw exists due to a failure to invalidate a previous
session ID when assigning an ID to a new session. An
attacker can exploit this, via a crafted request that
uses the requestedSessionSSL field to fixate the session
ID, to ensure that the user authenticates with a known
session ID, allowing the session to be subsequently
hijacked. (CVE-2015-5346)

- An information disclosure vulnerability exists in the
Manager and Host Manager web applications due to a flaw
in the index page when issuing redirects in response to
unauthenticated requests for the root directory of the
application. An unauthenticated, remote attacker can
exploit this to gain access to the XSRF token
information stored in the index page. (CVE-2015-5351)

- An information disclosure vulnerability exists that
allows a specially crafted web application to load the
StatusManagerServlet. An attacker can exploit this to
gain unauthorized access to a list of all deployed
applications and a list of the HTTP request lines for
all requests currently being processed. (CVE-2016-0706)

- A security bypass vulnerability exists due to a flaw
in the StandardManager, PersistentManager, and cluster
implementations that is triggered when handling
persistent sessions. An unauthenticated, remote attacker
can exploit this, via a crafted object in a session, to
bypass the security manager and execute arbitrary code.
(CVE-2016-0714)

- A flaw exists due to the setGlobalContext() method of
ResourceLinkFactory being accessible to web applications
even when run under a security manager. An
unauthenticated, remote attacker can exploit this to
inject malicious global context, allowing data owned by
other web applications to be read or written to.
(CVE-2016-0763)

Note that Nessus has not attempted to exploit these issues but has
instead relied only on the application's self-reported version number.

Solution :

Although version 8.0.31 fixes these issues, that version was not
officially released, and the vendor recommends upgrading to 8.0.32 or
later.
