-----------------------------------------
Hi James,
Now that OFBIZ-11329 is closed, here is my last patch [^OFBIZ-11306.patch]
Not much changes since your last (most of my recent work was on
setUserTimeZone):
* The cache size for the Tokens Map that stores the CSRF tokens,
removeEldestEntry is used to get above csrf.cache.size (in security.properties)
* By default the CSRF defense is enabled, developers need to disable it:
csrf-defense-enabled in requestHandler.properties
* Also some formatting, mostly in new files.
Some questions still pending:
* I did not remove changes in TopAppBar.ftl and AppBarClose.ftl. But why do we
need a crsf token there? It's about help, so only content, so is idempotent,
isn't?
* What about my point on RequestHandlerExceptionAllowExternalRequests?
* You wrote
{quote}Switched to UtilCache (instead of http sessions) to store tokens after
user login, as some pages contain links to other webapps e.g. acctg trans page
contains links to partymgr's viewprofile. Still using sessions to store tokens
for ajax and before user login.
{quote}
Could we not do the same for Ajax inter webapps calls? I understand that for
HTTP requests partyId is used after login. For Ajax requests we have not always
a such ID. Maybe we could use userLogin and PartyId which has (sometimes?/most
of the time?) present. Or put in a specific ID? To be continued...

> CRSF tokens are generated using SecureRandom class (maybe later a JWT with a
> "time out").
> They are stored in the user sessions (for AJAX calls and unauthenticated HTTP
> calls) or OFBiz UtilCache (for authenticated HTTP calls), and verified during
> POST request.
> # In *controllers* a new csrf-token attribute is added to the security tag to
> exempt or force CSRF token check.
> # In *Widget Forms* a hidden token field is auto-generated.
> # In *FTL form* a CSRF token is passed through <@ofbizUrl> to automatise the
> change. Using <@ofbizUrl> macro to generate the CSRF token means there is no
> need to manually add the CSRF token field to each form in the ftl files. It
> will save time for users doing custom implementation and maintenance. While
> there is CSRF token in the form URL, the token is invalidated during form
> submission. So it's uniqueand harmless even though the CSRF token of the form
> submission is shown in the browser address bar.
> # For *Ajax calls* an ajaxPrefilter function (observer on DOM ready) is added
> through OfbizUtil.js (itself called at start in decorators and such)
> # The html metadata is storing the csrf token used by JQuery AJAX. This token
> will not change to another value after it is consumed
> # Csrf tokens for the user are removed from the UtilCache when the user logs
> out or session invalidated.
> The general rule are as follows:
> * RequestMap configured with 'get' method will be exempted from CSRF token
> check.
> * RequestMap configured with 'post' or 'all' method will be subjected to CSRF
> token check. (Note there are discussions that RequestMap with ‘all’ method
> should also not be subjected to CSRF token check. This will be done after
> ensuring a separate uri is used when posting changes.)
> * "main" request URIs are exempted from CSRF token check.
> * Setting csrf-token to false or true on the Request Map will override the
> general rules above.
> To implement:
> * -Allow token map size to be configurable in properties.- OK that's done
> locally
> To Discuss:
> * Invalidate authenticated user session when CSRF token check fails.
> * Configure the general rules in a Service method (which will be run inside
> the constructor of RequestMap class) when determining the final
> securityCsrfToken value.
