James Yong commented on OFBIZ-11306:
------------------------------------

Hi Jacques,

Sorry about error in the test case. Can you comment out testGenerateTokenForNonAjax? It is a work in progress.
{quote}I suggest to add "If you are in dev mode you may set N to csrf-defense-enabled in security.property" at the end of the message "Invalid or missing CSRF token to path ..."
{quote}
Don't think it is good to suggest configuration to end-users.
 In the long run, we should exempt token check for request map when method is either 'get' or 'all'. Then user will see less of the "Invalid or missing CSRF token to path ..." error. At a later stage, we need to discuss whether to log out the user when csrf token is invalid. What do you think?
{quote}Just got this test errors also running {{gradlew --continuous}} (compiling is fine, only test errors):
{quote}
Can check findRequestMap method has protected modifier instead of private? I changed the access modifier to allow testing on the method, although I can try to use reflection instead..

> 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.
