HtmlUtil.escapeRedirect in Liferay Portal 7.3.1 through 7.4.2 can be circumvented by using multiple forward slashes, which allows remote attackers to redirect users to arbitrary external URLs via the (1) 'redirect` parameter (2) `FORWARD_URL` parameter, and (3) others parameters that rely on HtmlUtil.escapeRedirect.
