Description
A flaw was found in jackson-databind. FasterXML mishandles the interaction between serialization gadgets and typing. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
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
CVSS score applicability
The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.
Mitigation
The following conditions are needed for an exploit, we recommend avoiding all if possible:
- Deserialization from sources you do not control
enableDefaultTyping()@JsonTypeInfo usingid.CLASSorid.MINIMAL_CLASS`- avoid org.apache.commons.dbcp2.datasources.PerUserPoolDataSource and org.apache.commons.dbcp2.datasources.SharedPoolDataSource in the classpath
