Constructr CMS 3.03 Miltiple Remote Vulnerabilities (XSS/SQLi)
 
 
Vendor: phaziz interface design
Product web page: http://www.constructr-cms.org
Affected version: 3.03.0
 
Summary: ConstructrCMS is a new and fresh Content Management
System build with the Power of PHP and MySQL. The Backend is
mostly controlled by Ajax for a unique User Experience.
 
Desc: The CMS suffers from several vulnerabilities (SQL and XSS).
The sql issue can be triggered when the app tries to parse malicious
arguments to the 'page_id' in the /xmlOutput/constructrXmlOutput.content.xml.php
script with user input not validated. 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.
