CVE-2021-33326

Name of the Vulnerable Software and Affected Versions Liferay Portal versions 7.3.4 and earlier Liferay DXP 7.0 before fix pack 96 Liferay DXP 7.1 before fix pack 20 Liferay DXP 7.2 before fix pack 9

Description A cross-site scripting (XSS) issue in the Frontend JS module allows remote attackers to inject arbitrary web script or HTML via the title of a modal window. This enables attackers to execute malicious scripts on the client-side.

Recommendations For Liferay Portal versions 7.3.4 and earlier, update to a version later than 7.3.4. For Liferay DXP 7.0, apply fix pack 96 or later. For Liferay DXP 7.1, apply fix pack 20 or later. For Liferay DXP 7.2, apply fix pack 9 or later. As a temporary workaround, consider restricting user input for modal window titles to minimize the risk of exploitation.
