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.

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-6282-1 advisory.

    Jackson Henry discovered that Velocity Tools incorrectly handled certain inputs. If a user or an automated     system were tricked into opening a specially crafted input file, a remote attacker could possibly use this     issue to execute arbitrary code.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote host is affected by the vulnerability described in GLSA-202107-52 (Apache Velocity: Multiple vulnerabilities)
