A SQL injection in VirtueMart component 1.0.0 - 4.4.7 for Joomla allows authenticated attackers (administrator) to execute arbitrary SQL commands in the product management area in backend.
An XSS issue was discovered in VirtueMart before 3.2.14. All the textareas in the backend of the plugin can be closed by simply adding </textarea> to the value and saving the product/config. By editing back the product/config, the editor's browser will execute everything after the </textarea>, leading to a possible XSS.
Cross-site scripting (XSS) vulnerability in assets/js/vm2admin.js in the VirtueMart component before 3.0.8 for Joomla! allows remote attackers to inject arbitrary web script or HTML via vectors involving a "double encode combination of first_name, last_name and company."
