Hi All,
Tomcat Version : 9.0.75
Operating System: Windows and Linux
Bits: 64
Tomcat 9.0.75 not honoring session timeout configured in
tomcat/conf/web.xml for FORM Authentication and it is effecting customers.
==========================
<session-config>
<session-timeout>30</session-timeout> // 30 minutes
</session-config>
=========================
Verified the Tomcat source code
- FormAuthenticator overriding above configured session timeout
setting (30 minutes) with value (120 seconds)
- As per FormAuthenticator.Java, this change/issue started from
Tomcat Version : 9.0.74 for FORM Authentication and it overwrites the
original session-timeout value
- This issue/behavior not observed in 9.0.73
Verified the Tomcat documentation
- Verified the tomcat changelog, there is a fix/change went in
Tomcat 9.0.74 below related to FORM Based Authentication Session @
https://tomcat.apache.org/tomcat-9.0-doc/changelog.html, looks which is
causing this issue.
------------------------------------------------------------------------------------------------------------------------------
Harden the FORM authentication process against DoS attacks by using a
reduced session timeout if the FORM authentication process creates a
session. The duration of this timeout is configured by the
authenticationSessionTimeout attribute of the FORM authenticator. (markt)
-------------------------------------------------------------------------------------------------------------------------
Is it bug ? Could you please help/suggest.
Thanks
Channa
