Description:
Commonspot server is vulnerable to a vanilla XSS

Vulnerable server-side script: 'commonspot/utilities/longproc.cfm'

Unfiltered parameter: 'arbitrary'

Consequences:

An attacker may be able to cause execution of malicious scripting code in the browser of a victim user who clicks on a link to a RSA Authentication Agent login page. Such code would run within the context of the target domain.

This type of attack can result in non-persistent defacement of the target site, or the redirection of confidential information (i.e.: session IDs or passwords) to unauthorised third parties
