Liferay CMS Portal version 7.1.3 and 7.2.1 have a blind persistent cross-site scripting (XSS) vulnerability in the user name parameter to Calendar. An attacker can insert the malicious payload on the username, lastname or surname fields of its own profile, and the malicious payload will be injected and reflected in the calendar of the user who submitted the payload. An attacker could escalate its privileges in case an admin visits the calendar that injected the payload.
The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
