Description

Elgg contains a flaw that allows a remote cross-site scripting (XSS) attack. This flaw exists because the application does not validate the 'internalname', 'page', 'send_to' and 'container_guid' parameters upon submission to the engine/handlers/pagehandler.php script. This may allow a user to create a specially crafted URL that would execute arbitrary script code in a user's browser within the trust relationship between their browser and the server.
