Insufficient Session Expiration

CWE-613

The following snippet was taken from a J2EE web.xml deployment descriptor in which the session-timeout parameter is explicitly defined (the default value depends on the container). In this case the value is set to -1, which means that a session will never expire.


               
</web-app>

                     
</session-config>
<session-timeout>-1</session-timeout>
