Apache Tomcat < 7.0.67 Session Fixation

Medium Nessus Plugin ID 121118


The remote Apache Tomcat server is affected by a session fixation vulnerability.


According to its self-reported version number, the Apache Tomcat instance listening on the remote host is prior to 7.0.67. It is, therefore, affected by a session fixation vulnerability:

- 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.

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


Upgrade to Apache Tomcat version 7.0.67 or later.
