Description
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.
