Jacques Le Roux commented on OFBIZ-11306:
-----------------------------------------

Hi James,

Thanks for feedback.

bq. Do you have any link for further reading?
https://blog.clever-age.com/fr/2014/06/25/owasp-cross-site-request-forgery-csrf-ou-xsrf/ It's
in French but I guess it's readable when translated by Google or maybe better Deepl. I read
in comment that using an IP address can be a problem if the use is browsing throught Thor,
so maybe not a good idea finally. Remains the timeout, and maybe we can find another static
parameter to replace the IP as a JWT claim. Anyway all that is minor. A random value as you
propose is safe enough IMO. Just that we can't limit it in time. We can discuss that later
with the team...

> CRSF tokens are generated using SecureRandom class.
> 1) In widget form where a hidden token field is auto-generated.
> 2) In FTL form where a <@csrfTokenField> macro is used to generate the csrf token
field. 
> 3) In Ajax call where a <@csrfTokenAjax> macro is used to assign csrf token to
X-CSRF-Token in request header. 
> CSRF tokens are stored in the user sessions, and verified during POST request.
> A new attribute i.e. csrf-token is added to the security tag to exempt CSRF token check.
> Certain request path, like LookupPartyName, can be exempt from CSRF token check during
Ajax POST call.
