Multiple directory traversal vulnerabilities in ErfurtWiki R1.02b and earlier when register_globals is enabled allow remote attackers to include and execute arbitrary local files via a .. (dot dot) in the (1) ewiki_id and (2) ewiki_action parameters to fragments/css.php and possibly the (3) id parameter to the default URI. NOTE: the default URI is site-specific but often performs an include_once of ewiki.php.
