Description Pedro Sampaio 2021-04-01 17:42:53 UTC
In Eclipse Jetty 9.4.32 to 9.4.38, 10.0.0.beta2 to 10.0.1, and 11.0.0.beta2 to 11.0.1, if a user uses a webapps directory that is a symlink, the contents of the webapps directory is deployed as a static webapp, inadvertently serving the webapps themselves and anything else that might be in that directory.

Comment 11 Jonathan Christison 2021-04-19 10:50:22 UTC
This vulnerability is out of security support scope for the following products:
 * Red Hat JBoss Fuse 6
 * Red Hat JBoss A-MQ 6

Please refer to https://access.redhat.com/support/policy/updates/jboss_notes for more details.

Comment 12 Jonathan Christison 2021-04-19 16:11:24 UTC
Marking Red Hat Camel K as having a low impact, although Camel K distributes jetty artifacts through camel-jetty, camel-jetty itself is not available for use by the application developer, http functionality is provided by camel-k default runtime, Quarkus.

Comment 16 Todd Cullum 2021-04-27 20:00:57 UTC
Statement:

In OpenShift Container Platform (OCP), the hive/presto/hadoop components that comprise the OCP metering stack, ship the vulnerable version of jetty.
Since the release of OCP 4.6, the metering product has been deprecated [1], hence the affected components are marked as wontfix.
This may be fixed in the future.

[1] https://docs.openshift.com/container-platform/4.6/release_notes/ocp-4-6-release-notes.html#ocp-4-6-metering-operator-deprecated

Red Hat OpenStack Platform's OpenDaylight will not be updated for this flaw because it was deprecated as of OpenStack Platform 14 and is only receiving security fixes for Important and Critical flaws.

Red Hat CodeReady Studio 12 is not affected by this vulnerability because it does not ship a vulnerable version of jetty.
