INDEX I.ABOUT THE APPLICATION II. DESCRIPTION III.ANALYSIS IV. SAMPLE CODE V.FIX I. ABOUT THE APPLICATION iScriptsSocialWareisanaward-winning,easy to use socialnetworkingsoftwarethatenables you to create yourown social network like MySpace, Orkut, Friendster, Linkedin, Facebook, Hi5, etc. II. DESCRIPTION ThisCMSisaffected by multiple remote security flaws, such as SQL Injection, Arbitrary File upload, etc. These security flaws DO NOT require authentication. Other files may be vulnerable. III. ANALYSIS Summary: A) Multiple Arbitrary File Upload B) Multiple SQL Injection C) Multiple Blind SQL Injection D) Multiple Reflected and Stored XSS E) Information Disclosure A) Multiple Arbitrary File Upload The file's extension of the file senttojobs.php?step=4 usingthetxtResume parameter is not properly sanitised. Thedestinationfolderisjobs/resume, permission 777. There is no extension restriction. AnotherArbitraryFileUploadflawwasreported in a previous security advisory (2010-07-02): http://www.salvatorefresta.net/files/adv/iScripts%20SocialWare%202.2.x%20Arbitrary%20File%20Upload%20Vulnerability-02072010.txt event/function.phpis affected by the same arbitrary file upload flaw reported in the previous security flaws. It is possibletouploadaphpfileif the Content-Type is image/jpeg or image/gif and the file's extension is php5. The destination directory is event_category. manage_music.php is affectedby the same flaw reported in the previoussecurityadvisory. It is possible to upload aphpfileiftheContent-Type is allowed (audio/mpeg etc.). The destination directory is music/files. Also manage_videos.php,album.php (function.php), manage_networks.php use the same vulnerable upload method. B) Multiple SQL Injection event_thereactive.phpisincluded by events.php when the action parameter is set to show. In this script, the id parameter is not properly sanitised before being used in a SQL query.Toview the information without be redirected toanotherpagefromevents.php, the injection must be sent using the POST method instead of the GET method. This is possible because in the affected file, the id parameter is readed using the $_REQUEST array. event_create2.php is affected by the same bug.To exploit it, the action parameter must be set to create2. C) Multiple Blind SQL Injection TheId parameter in function.php when $_POST['status'] is settocreate2 is not properly sanitised before being usedina SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code. The affected query types are respectively an UPDATE anda SELECT. D) Multiple Reflected and Stored XSS Allformsthat allowHTML tags are vulnerable to stored XSS.Thereasonisthattherearenochecksabout javascript tags. Many reflected XSSare allowed but it is impossible use single/double quotes because of the escape. E) Information Disclosure phpinfo.php executes thePHPfunction'sphpinfo()that printsalotofinformationabout the server and path names. IV.
