Impact

There is a possibility to save XSS code in province field in the Checkout and Address Book and then execute it on these pages. The problem occurs when you open the address step page in the checkout or edit the address in the address book. This only affects the base UI Shop provided by Sylius.

Patches

The issue is fixed in versions: 1.12.16, 1.13.1 and above.

Workarounds

  1. Create new file assets/shop/sylius-province-field.js:
// assets/shop/sylius-province-field.js

function sanitizeInput(input) {
  const div = document.createElement('div');
  div.textContent = input;
  return div.innerHTML; // Converts text content to plain HTML, stripping any scripts
}

const getProvinceInputValue = function getProvinceInputValue(valueSelector) {
  return valueSelector == undefined ? '' : `value="${sanitizeInput(valueSelector)}"`;
};

$.fn.extend({
  provinceField() {
    const countrySelect = $('select[name$="[countryCode]"]');

    countrySelect.on('change', (event) => {
      const select = $(event.currentTarget);
      const provinceContainer = select.parents('.field').next('div.province-container');

      const provinceSelectFieldName = select.attr('name').replace('country', 'province');
      const provinceInputFieldName = select.attr('name').replace('countryCode', 'provinceName');

      const provinceSelectFieldId = select.attr('id').replace('country', 'province');
      const provinceInputFieldId = select.attr('id').replace('countryCode', 'provinceName');

      const form = select.parents('form');

      if (select.val() === '' || select.val() == undefined) {
        provinceContainer.fadeOut('slow', () => {
          provinceContainer.html('');
        });

        return;
      }

      provinceContainer.attr('data-loading', true);
      form.addClass('loading');

      $.get(provinceContainer.attr('data-url'), { countryCode: select.val() }, (response) => {
        if (!response.content) {
          provinceContainer.fadeOut('slow', () => {
            provinceContainer.html('');

            provinceContainer.removeAttr('data-loading');
            form.removeClass('loading');
          });
        } else if (response.content.indexOf('select') !== -1) {
          provinceContainer.fadeOut('slow', () => {
            const provinceSelectValue = getProvinceInputValue((
              $(provinceContainer).find('select > option[selected$="selected"]').val()
            ));

            provinceContainer.html((
              response.content
                .replace('name="sylius_address_province"', `name="${provinceSelectFieldName}"${provinceSelectValue}`)
                .replace('id="sylius_address_province"', `id="${provinceSelectFieldId}"`)
                .replace('option value="" selected="selected"', 'option value=""')
                .replace(`option ${provinceSelectValue}`, `option ${provinceSelectValue}" selected="selected"`)
            ));
            provinceContainer.addClass('required');
            provinceContainer.removeAttr('data-loading');

            provinceContainer.fadeIn('fast', () => {
              form.removeClass('loading');
            });
          });
        } else {
          provinceContainer.fadeOut('slow', () => {
            const provinceInputValue = getProvinceInputValue($(provinceContainer).find('input').val());

            provinceContainer.html((
              response.content
                .replace('name="sylius_address_province"', `name="${provinceInputFieldName}"${provinceInputValue}`)
                .replace('id="sylius_address_province"', `id="${provinceInputFieldId}"`)
            ));

            provinceContainer.removeAttr('data-loading');

            provinceContainer.fadeIn('fast', () => {
              form.removeClass('loading');
            });
          });
        }
      });
    });

    if (countrySelect.val() !== '') {
      countrySelect.trigger('change');
    }

    if ($.trim($('div.province-container').text()) === '') {
      $('select.country-select').trigger('change');
    }

    const shippingAddressCheckbox = $('input[type="checkbox"][name$="[differentShippingAddress]"]');
    const shippingAddressContainer = $('#sylius-shipping-address-container');
    const toggleShippingAddress = function toggleShippingAddress() {
      shippingAddressContainer.toggle(shippingAddressCheckbox.prop('checked'));
    };
    toggleShippingAddress();
    shippingAddressCheckbox.on('change', toggleShippingAddress);
  },
});
  1. Add new import in assets/shop/entry.js:
// assets/shop/entry.js
