Fixed In Version: jackson-databind 2.9.10, jackson-databind 2.10.0
Doc Type: If docs needed, set a value
Doc Text:
A flaw was discovered in FasterXML jackson-databind, where it would permit polymorphic deserialization of malicious objects using the xalan JNDI gadget when used in conjunction with polymorphic type handling methods such as `enableDefaultTyping()` or when @JsonTypeInfo is using `Id.CLASS` or `Id.MINIMAL_CLASS` or in any other way which ObjectMapper.readValue might instantiate objects from unsafe sources. An attacker could use this flaw to execute arbitrary code.

Description Pedro Sampaio 2019-10-03 13:40:32 UTC 
A flaw was found in jackson-databind before 2.9.10. New serialization gadgets were found regarding a class of the xalan package which may help in exploiting deserialization issues.

Upstream issue:

https://github.com/FasterXML/jackson-databind/issues/2469

Upstream patch:

https://github.com/FasterXML/jackson-databind/commit/998efd708284778f29d83d7962a9bd935c228317

Comment 1 Pedro Sampaio 2019-10-03 13:41:53 UTC 
Created jackson-databind tracking bugs for this issue:

Affects: fedora-all [bug 1758183]
Comment 5 Anten Skrabec 2019-10-18 21:36:04 UTC 
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.
Comment 13 Kunjan Rathod 2019-12-06 00:28:14 UTC 
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.
Comment 16 Paramvir jindal 2019-12-17 09:12:01 UTC 
Marking JDG as affected fix because the fix version seems to be jackson-databind 2.9.10 and JDG 7.3.4 (latest as of today) ships jackson-databind-2.9.9.3-redhat-00001.jar :

JDG/modules/system/add-ons/jdg/.overlays/layer-jdg-jboss-jdg-7.3.4.CP/com/fasterxml/jackson/core/jackson-databind/jdg-7.3/jackson-databind-2.9.9.3-redhat-00001.jar

Mitigation:

The following conditions are needed for an exploit, we recommend avoiding all if possible

* `enableDefaultTyping()`
* `@JsonTypeInfo using `id.CLASS` or `id.MINIMAL_CLASS`
