Multiple directory traversal vulnerabilities in Dokeos 1.8.5, and possibly earlier, allow remote attackers to (1) read portions of arbitrary files via a .. (dot dot) and a ..\ (dot dot backslash) in the lang parameter to main/exercice/hotspot_lang_conversion.php and (2) read arbitrary files via a .. (dot dot) in the doc_url parameter to main/exercice/Hpdownload.php.
