Description Michael Kaplan 2020-04-06 14:36:11 UTC
A vulnerability was found in Jackson-databind 2.x before 2.9.10.4 mishandles the interaction between serialization gadgets and typing, related to org.apache.openjpa.ee.WASRegistryManagedRuntime (aka openjpa).

Affects: fedora-all [bug 1821316]

Comment 7 Riccardo Schirone 2020-04-10 14:40:28 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`

Comment 23 Riccardo Schirone 2020-04-21 15:59:59 UTC
Statement:

Red Hat Satellite 6 does not enable polymorphic deserialization 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.

While OpenShift Container Platform's elasticsearch plugins do ship the vulnerable component, it doesn't do any of the unsafe things described in https://access.redhat.com/solutions/3279231. We may update the jackson-databind dependency in a future release.

The PKI module as shipped in Red Hat Enterprise Linux 8 does not enable polymorphic deserialization which is a required configuration for the vulnerability to be used, lowering the impact of the vulnerability for the Product. We may update the jackson-databind dependency in a future release.
