The CVE-2025-XXXX vulnerability is a reflected Cross-Site Scripting (XSS) flaw within Liferay Portal and Liferay DXP. It specifically exists in the `_com_liferay_users_admin_web_portlet_UsersAdminPortlet_assetTagNames` parameter. An authenticated attacker can craft a malicious URL containing a JavaScript payload within this parameter. When an authenticated administrator is tricked into clicking the link, the server reflects the payload unsanitized back into the user’s browser within the response. This causes the embedded script to execute in the context of the victim’s session, allowing the attacker to perform actions as that user.
Platform: Liferay Portal/DXP
Version: 7.4.0-7.4.3.132
Vulnerability: Reflected XSS
Severity: Moderate
date: 2025-08-20
Prediction: 2025-09-17
What Undercode Say:
`curl -i -s -k -X $’GET’ -H $’Cookie: JSESSIONID=target_session’ $’http://target/group/control_panel/manage?p_p_id=com_liferay_users_admin_web_portlet_UsersAdminPortlet&_com_liferay_users_admin_web_portlet_UsersAdminPortlet_assetTagNames=‘`
`grep -r “assetTagNames” /liferay/tomcat/webapps/ROOT/WEB-INF/src/`
How Exploit:
Craft malicious URL with JavaScript payload in the `assetTagNames` parameter. Social engineer an authenticated administrator to click the link. Payload executes within their browser session, hijacking their account to perform unauthorized actions.
