Apache Tomcat < 9.0.0.M3 Multiple Vulnerabilities

Medium Nessus Plugin ID 121125

Synopsis

The remote Apache Tomcat server is affected by multiple vulnerabilities.

Description

According to its self-reported version number, the Apache Tomcat instance listening on the remote host is prior to 9.0.0.M3. It is, therefore, affected by multiple vulnerabilities:

- An information disclosure vulnerability exists due to a failure to enforce access restrictions when handling directory requests that are missing trailing slashes. An unauthenticated, remote attacker can exploit this to enumerate valid directories. (CVE-2015-5345)

- 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 tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apache Tomcat version 9.0.0.M3 or later.
