Adobe Coldfusion 8 multiple linked XSS vulnerabilies
Description
Adobe ColdFusion Server 8 contains multiple linked Cross-Site Scripting (XSS) and Cross-Site Request Forgery (XSRF) vulnerabilities that allow attackers to inject malicious scripts into web pages viewed by other users.
When exploited, these vulnerabilities enable attackers to execute arbitrary JavaScript code in the context of a victim's browser session. Because browsers cannot distinguish between legitimate application code and injected malicious scripts, the attacker's code executes with the same privileges as the trusted application, potentially compromising user sessions, cookies, and sensitive data.
