Name of the Vulnerable Software and Affected Versions Liferay Portal versions 7.1.0 through 7.3.2 Liferay DXP versions 7.1 before fix pack 19 Liferay DXP versions 7.2 before fix pack 6

Description The Layout module in the affected software exposes the CSRF token in URLs, allowing man-in-the-middle attackers to obtain the token and conduct Cross-Site Request Forgery (CSRF) attacks via the p auth parameter.

Recommendations For Liferay Portal versions 7.1.0 through 7.3.2, update to a version that includes the fix for the Layout module. For Liferay DXP versions 7.1 before fix pack 19, apply fix pack 19 or later. For Liferay DXP versions 7.2 before fix pack 6, apply fix pack 6 or later. As a temporary workaround, consider restricting access to the Layout module to minimize the risk of exploitation.
