[原文]The image gallery (imagegallery) component in Exponent CMS 0.96.3 and later versions does not properly check the MIME type of uploaded files, with unknown impact from the preview icon, possibly involving injection of HTML.
Exponent CMS contains a flaw that allows a remote cross-site scripting (XSS) attack. This flaw exists because the application does not validate the mime type checking during uploads upon submission to the image gallery 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.
OSVDB is not aware of a solution for this vulnerability.
