Macromedia ColdFusion MX 6.1 Template Handling Privilege Escalation Vulnerability

                                                source: http://www.securityfocus.com/bid/11316/info

Reportedly Macromedia ColdFusion MX is affected by privilege escalation vulnerability when handling templates. This issue is due to an access validation error that allows a user to perform actions with administrator privileges.

An attacker may exploit this issue to gain administrative privileges on a computer running the vulnerable application.
