A typo in the administrator permission check in the ACL Manager plugin (plugins/acl/ajax.php) in DokuWiki before 2009-12-25b allows remote attackers to gain privileges and access closed wikis by editing current ACL statements, as demonstrated in the wild in January 2010.
Multiple cross-site request forgery (CSRF) vulnerabilities in the ACL Manager plugin (plugins/acl/ajax.php) in DokuWiki before 2009-12-25c allow remote attackers to hijack the authentication of administrators for requests that modify access control rules, and other unspecified requests, via unknown vectors.
inc/init.php in DokuWiki 2009-02-14, rc2009-02-06, and rc2009-01-30, when register_globals is enabled, allows remote attackers to include and execute arbitrary local files via the config_cascade[main][default][] parameter to doku.php. NOTE: PHP remote file inclusion is also possible in PHP 5 using ftp:// URLs.
