java/org/apache/catalina/authenticator/FormAuthenticator.java in the form authentication feature in Apache Tomcat 6.0.21 through 6.0.36 and 7.x before 7.0.33 does not properly handle the relationships between authentication requirements and sessions, which allows remote attackers to inject a request into a session by sending this request during completion of the login form, a variant of a session fixation attack.

This flaw allows an attacker to circumvent a session fixation prevention mechanism which was implemented in tomcat 5.5.x >= 5.5.29, 6.0.x >= 6.0.21 and 7.x. Earlier versions of tomcat do not include this mechanism, and are therefore not affected by this flaw. JBoss Web as included in JBoss 5.x products also does not include this mechanism, and is not affected by this flaw.
