Joomla Canteen Component Multiple Vulnerabilities

Description

Salvatore Fresta has discovered multiple vulnerabilities in the Canteen component for Joomla, which can be exploited by malicious users to conduct SQL injection attacks and by malicious people to disclose potentially sensitive information.
1) Input passed via the "mealid" parameter to index.php (when "option" is set to "com_canteen", "view" is set to "menu", "controller" is set to "menu", and "task" is set to "saveOrder", "removeOrder", or "saveFromBursa") is not properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
2) Input passed to the "controller" parameter in index.php (when "option" is set to "com_canteen") is not properly verified before being used to include files. This can be exploited to include arbitrary files from local resources via directory traversal attacks and URL-encoded NULL bytes.
The vulnerabilities are confirmed in version 1.0. Other versions may also be affected.

Vulnerable Products

Vulnerable Software:
Canteen 1.x (component for Joomla)

Solution

Edit the source code to ensure that input is properly sanitised and verified.
