Description

Mitigation: The following conditions are needed for an exploit, we recommend avoiding all if possible: * Deserialization from sources you do not control * `enableDefaultTyping()` * `@JsonTypeInfo using `id.CLASS` or `id.MINIMAL_CLASS` * avoid org.apache.commons.dbcp2.datasources.PerUserPoolDataSource and org.apache.commons.dbcp2.datasources.SharedPoolDataSource in the classpath External References: https://github.com/FasterXML/jackson-databind/issues/2986 https://cowtowncoder.medium.com/on-jackson-cves-dont-panic-here-is-what-you-need-to-know-54cd0d6e8062 Statement: The following Red Hat products do ship the vulnerable component, but do not enable the unsafe conditions needed to exploit, lowering their vulnerability impact: * JBoss Data Grid 7 * Business Process Management Suite 6 * Business Rules Management Suite 6 * JBoss Data Virtualization 6 * Red Hat Fuse Service Works 6 * Red Hat OpenStack Platform * Red Hat OpenShift containers: ose-metering-hadoop, ose-metering-hive, ose-logging-elasticsearch5, ose-logging-elasticsearch6 These products may update the jackson-databind dependency in a future release. In Red Hat Openshift 4 there are no plans to maintain the ose-logging-elasticsearch5 container, hence it has been marked wontfix at this time and may be fixed in a future update. The following Red Hat products ship OpenDaylight, which contains the vulnerable jackson-databind, but do not expose jackson-databind in a way that would make it exploitable * Red Hat OpenStack Platform 13 As such, Red Hat will not be providing a fix for OpenDaylight at this time. The following Red Hat products are not affected by this flaw because they use a more recent version of jackson-databind that does not contain the vulnerable code: * CodeReady Studio 12.16.0 * Red Hat Enterprise Linux 8 * Red Hat Enterprise Virtualization * Red Hat Satellite 6 * Red Hat OpenShift container: ose-metering-presto This issue has been addressed in the following products: Red Hat OpenShift Container Platform 4.6 Via RHSA-2021:1230 https://access.redhat.com/errata/RHSA-2021:1230 This bug is now closed. Further updates for individual products will be reflected on the CVE page(s): https://access.redhat.com/security/cve/cve-2020-35490 |
