"Liferay Portal 7.3.2 prior to 7.3.6 is affected by a cross-site scripting (XSS) vulnerability in its redirect module 
component due to improper validation of user-supplied input before returning it to users. An unauthenticated, remote 
attacker can exploit this, by convincing a user to click a specially crafted URL, to execute arbitrary script code in
a user's browser session.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
