[原文]Multiple cross-site scripting (XSS) vulnerabilities in Joomla! before 1.0.10 allow remote attackers to inject arbitrary web script or HTML via unspecified parameters involving the (1) getUserStateFromRequest function, and the (2) SEF and (3) com_messages modules.
Joomla! contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate input upon submission to the 'SEF' functionality. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.
Upgrade to version 1.0.10 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
