Huh? You mean all those href="javascript:submitForm()" stuff has been
removed?

No, and that's the real issue... I think it will remains, except if we
find another way to avoid XSS from FTL files. I don't feel it will
change...

I don't understand how changing a form's submit button to a link that
calls a submit function protects us from XSS attacks.

Just have a look at one of the patches at
https://issues.apache.org/jira/browse/OFBIZ-2330 and you should get it

it was not forms that were changed but plain URL (get method)

The idea is before we had something like
<a
href='<@ofbizUrl>request?param1=${param1Value}&param2=${param2Value}&....</@ofbizUrl>>${uiLabelMap....}</a></div></td>

So we had parameters in an URL (ie a GET type method) and this could be
exploited when the request was a Create Update or Delete type service
(no pb for Read), ie to get an access to the DB.

We have now.
<form name= "request" method= "post" action=
"<@ofbizUrl>request</@ofbizUrl>">
<input type= "hidden" name= "param1" value= "${param1Value}"/>
<input type= "hidden" name= "param2" value= "${param2Value}"/>
<a href='javascript:document.request.submit()'>${uiLabelMap...}</a>
</form>
As it's a POST request type method with hidden parameters included in a
javascript call parameters it's not possible to use XSS Injection (you
can't hack the URL from outside to inject a script in it). Just try it
if you want to be sure...

This is explained clearly at
http://www.testingsecurity.com/how-to-test/injection-vulnerabilities/XSS-Injection
section "How to test for XSS Injection vulnerabilities"

One thing I'm not quire sure though is why we use javascript calls
instead of simple submit buttons (almost your question ;o).

That was EXACTLY my question.

Right, but most of the changes which introduced those js calls were not done on 
forms but plain URLs. That's why I explained it
all... For instance CopyAgreement.ftl has not been changed...
But yes, I think we could replace them by simple submit buttons. I can see not 
reasons why we should not.

BTW I have just tried with
deletePartyContactMechPurpose_${partyContactMechPurpose.contactMechPurposeTypeId}
 in
specialpurpose/ecommerce/webapp/ecommerce/customer/editcontactmech.ftl and it 
works well. I replaced
<!--a href='javascript:document.deletePartyContactMechPurpose_${partyContactMechPurpose.contactMechPurposeTypeId}.submit()' class='button'>&nbsp;${uiLabelMap.CommonDelete}&nbsp;</a-->
by
<input type="submit" name="deletePartyContactMechPurpose_${partyContactMechPurpose.contactMechPurposeTypeId}" class='button' value="&nbsp;${uiLabelMap.CommonDelete}&nbsp;"/>

any differences, any security error messages...

Maybe I miss something (XSS reinforced security?). But, like you, I can't see 
what! (I specifically chosen a dynamic input name)
