In LifeRay Portal CE 7.1.0 through 7.2.1 GA2, the First Name, Middle Name, and Last Name fields for user accounts in MyAccountPortlet are all vulnerable to a persistent XSS issue. Any user can modify these fields with a particular XSS payload, and it will be stored in the database. The payload will then be rendered when a user utilizes the search feature to search for other users (i.e., if a user with modified fields occurs in the search results). This issue was fixed in Liferay Portal CE version 7.3.0 GA1.
In Liferay Portal before 7.1 CE GA4, an XSS vulnerability exists in the SimpleCaptcha API when custom code passes unsanitized input into the "url" parameter of the JSP taglib call <liferay-ui:captcha url="<%= url %>" /> or <liferay-captcha:captcha url="<%= url %>" />. Liferay Portal out-of-the-box behavior with no customizations is not vulnerable.
An issue was discovered in Liferay Portal CE 7.1.2 GA3. An attacker can use Liferay's Groovy script console to execute OS commands. Commands can be executed via a [command].execute() call, as demonstrated by "def cmd =" in the ServerAdminPortlet_script value to group/control_panel/manage. Valid credentials for an application administrator user account are required. NOTE: The developer disputes this as a vulnerability since it is a feature for administrators to run groovy scripts and therefore not a design flaw
Liferay 6.2.x and before has an FCKeditor configuration that allows an attacker to upload or transfer files of dangerous types that can be automatically processed within the product's environment via a browser/liferay/browser.html?Type= or html/js/editor/fckeditor/editor/filemanager/browser/liferay/browser.html URI. NOTE: the vendor disputes this issue because file upload is an expected feature, subject to Role Based Access Control checks where only authenticated users with proper permissions can upload files
Cross-site scripting (XSS) vulnerability in the /html/portal/flash.jsp page in Liferay Portal CE 7.0 GA4 and older allows remote attackers to inject arbitrary web script or HTML via a javascript: URI in the "movie" parameter.
XSS exists in Liferay Portal before 7.0 CE GA4 via a crafted redirect field to modules/apps/foundation/frontend-js/frontend-js-spa-web/src/main/resources/META-INF/resources/init.jsp.
