A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.0.0 through 2.9.10. When Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint and the service has the commons-dbcp (1.4) jar in the classpath, and an attacker can find an RMI service endpoint to access, it is possible to make the service execute a malicious payload. This issue exists because of org.apache.commons.dbcp.datasources.SharedPoolDataSource and org.apache.commons.dbcp.datasources.PerUserPoolDataSource mishandling.

Created jackson-databind tracking bugs for this issue: Affects: fedora-all [bug 1758188]
Statement: Satellite 6 does not enable polymorphic unmarshmalling, which is a required configuration for the vulnerability to be used. We may update the jackson-databind dependency in a future release. Red Hat OpenStack Platform ships OpenDaylight, which contains the vulnerable jackson-databind. However, OpenDaylight does not expose jackson-databind in a way that would make it vulnerable, lowering the impact of the vulnerability for OpenDaylight. As such, Red Hat will not be providing a fix for OpenDaylight at this time.
This issue has been addressed in the following products: Red Hat Openshift Application Runtimes Vert.x 3.8.3 Via RHSA-2019:3901 https://access.redhat.com/errata/RHSA-2019:3901
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-2019-16942
Marking RHSSO as affected fix because the fix version seems to be greater than jackson-databind 2.9.10 and RHSSO 7.3.4 (latest as of today) ships jackson-databind-2.9.9.3-redhat-00001.jar.
This vulnerability is out of security support scope for the following products: * Red Hat JBoss BPMS 6 * Red Hat JBoss Data Virtualization & Services 6 Please refer to https://access.redhat.com/support/policy/updates/jboss_notes for more details.
