DescriptionCVE.org

SessionClicks in Liferay Portal 7.0.0 through 7.4.3.21, and Liferay DXP 7.4 GA through update 9, 7.3 GA through update 25, and older unsupported versions does not restrict the saving of request parameters in the HTTP session, which allows remote attackers to consume system memory leading to denial-of-service (DoS) conditions via crafted HTTP requests.
