A cross-site scripting flaw was found in the way jQuery dialogs handling functionality of ownCloud, a private file synchronization tool and share server, performed sanitization of the file name arguments in the filepicker module. A remote attacker could provide a specially-crafted web page that, when visited would lead to arbitrary HTML or web script execution in the context of the ownCloud user's session.
