Florent Guillaume updated NXP-6111:
-----------------------------------
Impact type: [Deployment change]
> Memory Leak And Security hole in ClientLoginModule
> --------------------------------------------------
>
> Key: NXP-6111
> URL: https://jira.nuxeo.org/browse/NXP-6111
> Project: Nuxeo Enterprise Platform
> Issue Type: Bug
> Affects Versions: 5.4.0.1
> Reporter: Bogdan Stefanescu
> Assignee: Bogdan Stefanescu
> Priority: Critical
> Fix For: 5.4.1
>
>
> The ClientLoginModule is the JAAS login module used on distribution others
> than JBoss.
> Memory leak on tomcat distribution:
> The LoginStackCleaner filter must be used to reset the ogin stack after each
> HTTP request - but it is not declared in tomcat distribution.
> Security Hole (on tomcat distribution):
> When using Open ULRs (see extension point
> org.nuxeo.ecm.platform.ui.web.auth.service.PluggableAuthenticationService#openUrl)
> and creating core sessions will use the context of the last user logged in
> the current thread (thread local variable) because the filter is not
> registered to clear the thread local login stack.
> Also, e must enforce the a session creation - and throw an exception if
> someone want to create a new session but no security context exists (not
> logged in).
> The same should be done in webengine context to avoid creating a session if
> current principal is null.
> Here is a list of modifications that needs to be done:
> 1. In LocalSession.createSession - add a check on principal and throw an
> exception if it is null.
> 2. AbstractWebContext.initializeBindings - add a check on principal to avoid
> binding a coresession if the principal is null.
> 3. Create a new project nuxeo-platform-login-default that deploy the login
> stack cleanup filter and the clientloginmodule web propagator. Remove
> config/authentication-config.xml file from tomcat distribution (and jetty
> one) - since it will be put in the new project.
