Description Guilherme de Almeida Suckevicz 2021-01-07 19:47:03 UTC
FasterXML jackson-databind 2.x before 2.9.10.8 mishandles the interaction between serialization gadgets and typing, related to org.apache.tomcat.dbcp.dbcp2.datasources.PerUserPoolDataSource.

Comment 4 Przemyslaw Roguski 2021-01-08 10:30:48 UTC
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: oadd.org.apache.commons.dbcp.cpdsadapter.DriverAdapterCPDS, org.apache.commons.dbcp2.cpdsadapter.DriverAdapterCPDS, org.apache.tomcat.dbcp.dbcp.cpdsadapter.DriverAdapterCPDS, org.apache.tomcat.dbcp.dbcp2.cpdsadapter.DriverAdapterCPDS, org.docx4j.org.apache.xalan.lib.sql.JNDIConnectionPool, org.apache.tomcat.dbcp.dbcp2.datasources.PerUserPoolDataSource, org.apache.tomcat.dbcp.dbcp2.datasources.SharedPoolDataSource, org.apache.tomcat.dbcp.dbcp.datasources.PerUserPoolDataSource, org.apache.tomcat.dbcp.dbcp.datasources.SharedPoolDataSource, com.newrelic.agent.deps.ch.qos.logback.core.db.JNDIConnectionSource, com.newrelic.agent.deps.ch.qos.logback.core.db.DriverManagerConnectionSource

Comment 9 RaTasha Tillery-Smith 2021-01-12 15:55:22 UTC
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, therefore 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
