Multiple directory traversal vulnerabilities in Dokeos 1.6 and earlier, and possibly Claroline, allow remote attackers to (1) delete arbitrary files or directories via the delete parameter to claroline/scorm/scormdocument.php, (2) move arbitrary files via the move_to and move_file parameters to claroline/document/document.php, or determine the existence of arbitrary files via the file parameter to (3) claroline/scorm/showinframes.php or (4) claroline/scorm/contents.php.
