Root Cause Analysis

The vulnerability is a reflected cross-site scripting (XSS) issue in Liferay Portal, specifically within the Dynamic Data Mapping module. The root cause is the lack of input sanitization for the definition parameter in the RenderStructureFieldMVCResourceCommand class.

The analysis of the provided commits, particularly 9e0026c8aa444937a2bfd079bcca35ab3dd18f5a and e83d102bf00af3aa4396c1fc5a1d6b3842ccaeb1, reveals that the getDDMFormField method (previously named _getDDMFormField) was responsible for processing the tainted definition parameter. The fix involves wrapping the ParamUtil.getString call with HtmlUtil.escapeAttribute to neutralize any malicious scripts.

The doServeResource method is the entry point that receives the malicious request and calls getDDMFormField. Therefore, both functions would appear in a runtime profile during exploitation. The vulnerability allows an authenticated attacker to inject arbitrary JavaScript code, which will be executed in the context of the victim's browser.
