Miggo AIRoot Cause Analysis

The analysis of the provided security patch (commit a659c94bcfb218e5e5bb3e2cf7efa20a5abc10ed) clearly indicates a reflected cross-site scripting (XSS) vulnerability within the doServeResource method of the RenderStructureFieldMVCResourceCommand class. The vulnerability is a classic example of improper output encoding, where user-controllable input, passed via the _com_liferay_dynamic_data_mapping_web_portlet_DDMPortlet_definition parameter, is rendered into the HTML page without being sanitized. The patch applies the HtmlUtil.escapeAttribute function to the rendered HTML, which is the standard mitigation for this type of XSS flaw. Therefore, the doServeResource function is the primary vulnerable function that would appear in a runtime profile during the exploitation of this CVE. The root cause is the failure to sanitize data that is reflected back to the user.

Vulnerable functions

com.liferay.dynamic.data.mapping.web.internal.portlet.action.RenderStructureFieldMVCResourceCommand.doServeResource
modules/apps/dynamic-data-mapping/dynamic-data-mapping-web/src/main/java/com/liferay/dynamic/data/mapping/web/internal/portlet/action/RenderStructureFieldMVCResourceCommand.java
The vulnerability lies in the `doServeResource` method, which handles the rendering of dynamic data mapping form fields. Before the patch, the output of the `ddmFormFieldRenderer.render` method was directly written to the HTTP response without proper escaping. This allowed an attacker to inject malicious JavaScript code through the `_com_liferay_dynamic_data_mapping_web_portlet_DDMPortlet_definition` parameter, which would then be executed in the victim's browser. The patch mitigates this by wrapping the output of the `render` method with `HtmlUtil.escapeAttribute`, which neutralizes any potentially harmful scripts.
