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.
