TYPO3 Core

Could you check if this is related to / solved by

https://forge.typo3.org/issues/84253 / https://review.typo3.org/#/c/56142/ ?

hi,

no, it seems it's not directly related to that issue.

Because here we have another JavaScript File.

In fe_login e.g we use the File
typo3_src-8.7.11/typo3/sysext/rsaauth/Resources/Public/JavaScript/RsaEncryption.js
and not
typo3_src-8.7.11/typo3/sysext/rsaauth/Resources/Public/JavaScript/RsaEncryptionModule.js

The problem is the way the submit Fields are fetched in Javascript, in this part, in RsaEncryption.js line 130

...
    for (var i = *document.forms*.length; i--;) {
      var form = document.forms[i];
      for (var j = form.elements.length; j--;) {
        var field = form.elements[j];
        if (field.nodeName.toLowerCase() === 'input') {
          var dataAttribute = field.getAttribute('data-rsa-encryption');
          if (dataAttribute || dataAttribute === '' && field.outerHTML.match(/ data-rsa-encryption=""/)) {
            if (!form.rsaEncryption) {

             * form.rsaEncryption = new rsaEncryption(form);*

              if (form.addEventListener) {
                form.addEventListener('submit', form.rsaEncryption.handleFormSubmitRequest, false);
              } else if (form.attachEvent) {
                form.attachEvent('onsubmit', form.rsaEncryption.handleFormSubmitRequest);
              }
            }
            form.rsaEncryption.fields.push(field);
          }
        }
      }
    }

We use "document.forms" to get all forms on page and in which we later search for the submit button
But: type="image" is not part of that

The elements which are included by HTMLFormElement.elements and HTMLFormElement.length are:

<button>
<fieldset>
<input> (with the exception that any whose type is "image" are omitted for historical reasons)
<object>
<output>
<select>
<textarea>
No other elements are included in the list returned by elements, which makes it an excellent way to get at the elements most important when processing forms.

With this commit we changed the submit handling: https://github.com/TYPO3/TYPO3.CMS/commit/a0e51ca70b9d8bc343acc0d178a9ba4b9095b94b

now the form is not simply sent, but it is searched for a submit button and clicked

hi,

this could be a possible solution:
as descriped here: https://developer.mozilla.org/en-US/docs/Web/API/HTMLFormElement/elements
HTMLFormElement.elements get this fields "button ,fieldset ,input ,object ,output ,select ,textarea".
So we get the fields ourselves with querySelectorAll and use it like this:

    // Submit the form again but now with encrypted values
       var formElements = rsaEncryption.form.querySelectorAll('button ,fieldset ,input ,object ,output ,select ,textarea'); 
      for (var j = formElements.length; j--;) {
        var submitField = formElements[j];
        if ((['input', 'button'].indexOf(submitField.nodeName.toLowerCase()) > -1)
          && (['submit', 'image', 'button'].indexOf(submitField.type.toLowerCase()) > -1)
        ) {
          submitField.click();
        }
      }
