This applies to applications that allow untrusted users to upload/modify velocity templates running Apache Velocity Engine versions up to 2.2.

--- Comment #8 from Mark Cooper mcooper@redhat.com --- Statement:
OpenShift Container Platform (OCP) openshift-logging/elasticsearch6-rhel8 container does contain a vulnerable version of velocity, however the references to the library only occur in the x-pack component which is an enterprise only feature of Elasticsearch - hence it has been marked as wontfix as this time and may be fixed in a future release.

--- Doc Text *updated* by Eric Christensen sparks@redhat.com --- A flaw was found in velocity. An attacker, able to modify Velocity templates, may execute arbitrary Java code or run arbitrary system commands with the same privileges as the account running the Servlet container. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

* Velocity as shipped with Red Hat Enterprise Linux 6 is not affected because it does not contain the vulnerable code.
* Velocity as shipped with Red Hat Enterprise Linux 7 contains a vulnerable version, but it is used as a dependency for IdM/ipa, which does not use the vulnerable functionality. It has been marked as Moderate for this reason.
* Although velocity shipped in Red Hat Enterprise Linux 8's pki-deps:10.6 for IdM/ipa is a vulnerable version, the vulnerable code is not used by pki. It has been marked as Low for this reason.

--- Comment #25 from Jonathan Christison jochrist@redhat.com --- Marking Red Hat JBoss A-MQ 6 as having a low impact, although the vulnerable artifact(s) are distributed with the product they are not used
This vulnerability is out of security support scope for the following products: * Red Hat JBoss A-MQ 6
Please refer to https://access.redhat.com/support/policy/updates/jboss_notes for more details.

--- Comment #27 from Jonathan Christison jochrist@redhat.com --- Marking Red Hat JBoss Fuse 6 and Red Hat Fuse 7 and Red Hat Integration Camel K as having a moderate impact, this is because components using the affected versions of velocity, namely camel-velocity does not allow, by default, use of templates derived from unprivileged mutable/dynamic sources ie. It does not allow generation or modification of templates from a source an attacker may control perquisite of this attack.
Customers using camel velocity with `allowTemplateFromHeader` or `allowContextMapAll` set to true are strongly advised to either disable the dynamic template functionality or ensure the templates are from a source that is not derived from unprivileged user input.
