This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site. 2) The ClanSphere CKEditor component mods/ckeditor/filemanager/connectors/php/upload.php allows the upload of files with arbitrary extensions, which can be exploited to upload arbitrary files and e.g. execute arbitrary PHP code. The vulnerabilities are confirmed in 2010.3. Other versions may also be affected. SOLUTION: Edit the source code to ensure that input is properly sanitised and file upload is properly restricted.
