Apache Tomcat Session Fixation

Apache Tomcat Session Fixation
Posted Feb 22, 2016
Authored by Mark Thomas | Site tomcat.apache.org

When recycling the Request object to use for a new request, the requestedSessionSSL field was not recycled. This meant that a session ID provided in the next request to be processed using the recycled Request object could be used when it should not have been. This gave the client the ability to control the session ID. In theory, this could have been used as part of a session fixation attack but it would have been hard to achieve as the attacker would not have been able to force the victim to use the 'correct' Request object. It was also necessary for at least one web application to be configured to use the SSL session ID as the HTTP session ID. This is not a common configuration. Apache Tomcat versions 7.0.5 through 7.0.65, 8.0.0.RC1 through 8.0.30, and 9.0.0.M1 are affected.

Description:
When recycling the Request object to use for a new request, the
requestedSessionSSL field was not recycled. This meant that a session ID
provided in the next request to be processed using the recycled Request
object could be used when it should not have been. This gave the client
the ability to control the session ID. In theory, this could have been
used as part of a session fixation attack but it would have been hard to
achieve as the attacker would not have been able to force the victim to
use the 'correct' Request object. It was also necessary for at least one
web application to be configured to use the SSL session ID as the HTTP
session ID. This is not a common configuration.

Mitigation:
Users of affected versions should apply one of the following mitigations
- - Upgrade to Apache Tomcat 9.0.0.M3 or later
(9.0.0.M2 has the fix but was not released)
