Open Source Point of Sale is a web based point-of-sale application written in PHP using CodeIgniter framework. Prior to 3.4.3, a Stored Cross-Site Scripting (XSS) vulnerability exists in the Stock Locations configuration feature. The application fails to properly sanitize user input supplied through the stock_location parameter, allowing attackers to inject malicious JavaScript code that is stored in the database and executed when rendered in the Employees interface. This vulnerability is fixed in 3.4.3.
