Target Milestone: ---
Classification: Other
The default error page for VelocityView in Apache Velocity Tools prior to 3.1
reflects back the vm file that was entered as part of the URL. An attacker can
set an XSS payload file as this vm file in the URL which results in this
payload being executed. XSS vulnerabilities allow attackers to execute
arbitrary JavaScript in the context of the attacked website and the attacked
user. This can be abused to steal session cookies, perform requests in the name
of the victim or for phishing attacks.
