Description Jan Lieskovsky 2013-02-08 14:55:29 UTC

A cross-site scripting (XSS) flaws were round in the way Round Cube Webmail, a browser-based multilingual IMAP client, performed sanitization of 'data' and 'vbscript' URLs. A remote attacker could provide a specially-crafted URL that, when opened would lead to arbitrary JavaScript, VisualBasic script or HTML code execution in the context of Round Cube Webmail's user session.
