In conclusion, Concrete CMS v.9.2.1 has been identified to harbor multiple Cross Site Scripting (XSS) vulnerabilities, particularly with regards to its Header/Footer tracking codes. While the vendor disputes the existence of this vulnerability due to its intentional customization feature, as well as the HttpOnly session cookie configuration, users should remain vigilant about potential injection of malicious scripts. To mitigate risk, administrators should validate and sanitize inputs, while also applying proper output encoding techniques to prevent malicious code execution. Regularly updating, patching, and monitoring the CMS will also contribute to a more secure environment.
