[原文]Cross-site scripting (XSS) vulnerability in Movable Type before 3.2 allows remote attackers to inject arbitrary web script or HTML via the (1) title, (2) category, (3) body, (4) extended body, and (5) excerpt form fields in new blog entries.
Movable Type contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate multiple variables upon submission to the scripts when creating new blog entries. 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 3.2 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
