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 ehcache 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.	Story Points:	---

Description Pedro Sampaio 2019-10-03 13:14:34 UTC

A flaw was found in jackson-databind before 2.9.10. New serialization gadgets were found regarding a class of the ehcache package which may help in exploiting deserialization issues.

Upstream issue:

https://github.com/FasterXML/jackson-databind/issues/2460

Upstream patch:

https://github.com/FasterXML/jackson-databind/commit/191a4cdf87b56d2ddddb77edd895ee756b7f75eb

Comment 1 Pedro Sampaio 2019-10-03 13:14:57 UTC

Created jackson-databind tracking bugs for this issue:

Affects: fedora-all [bug 1758168]

Comment 4 Anten Skrabec 2019-10-16 21:58:05 UTC

Statement: 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 9 errata-xmlrpc 2019-10-24 09:18:31 UTC

This issue has been addressed in the following products:

  Red Hat JBoss AMQ

Via RHSA-2019:3200 https://access.redhat.com/errata/RHSA-2019:3200

Comment 10 Product Security DevOps Team 2019-10-24 12:51:34 UTC

This bug is now closed. Further updates for individual products will be reflected on the CVE page(s):

Comment 11 Paramvir jindal 2019-11-19 11:44:16 UTC

Marking RHSSO as affected fix because the fix version seems to be
jackson-databind 2.9.10 and RHSSO 7.3.4 (latest as of today) ships
jackson-databind-2.9.9.3-redhat-00001.jar.

Comment 16 Kunjan Rathod 2019-12-06 00:54:40 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 36 Jason Shepherd 2021-03-17 01:33:17 UTC

Statement:

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.

Red Hat OpenShift Container Platform does ship the vulnerable component, but does not enable the unsafe conditions needed to exploit, lowering their vulnerability impact.
