Doc Text:
A flaw was discovered in FasterXML jackson-databind, where it would permit polymorphic deserialization of malicious objects using the commons-dbcp 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 13:52:26 UTC
A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.0.0 through 2.9.10. When Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint and the service has the commons-dbcp (1.4) jar in the classpath, and an attacker can find an RMI service endpoint to access, it is possible to make the service execute a malicious payload. This issue exists because of org.apache.commons.dbcp.datasources.SharedPoolDataSource and org.apache.commons.dbcp.datasources.PerUserPoolDataSource mishandling.

Comment 1 Pedro Sampaio 2019-10-03 13:52:48 UTC
Created jackson-databind tracking bugs for this issue:

Affects: fedora-all [bug 1758188]

Comment 7 Anten Skrabec 2019-10-29 21:38:44 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 8 errata-xmlrpc 2019-11-18 14:41:07 UTC
This issue has been addressed in the following products:

  Red Hat Openshift Application Runtimes Vert.x 3.8.3

Via RHSA-2019:3901 https://access.redhat.com/errata/RHSA-2019:3901

Comment 9 Product Security DevOps Team 2019-11-18 18:51:17 UTC
This bug is now closed. Further updates for individual products will be reflected on the CVE page(s):

https://access.redhat.com/security/cve/cve-2019-16942

Comment 10 Paramvir jindal 2019-11-19 12:18:26 UTC
Marking RHSSO as affected fix because the fix version seems to be greater than 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 15 Kunjan Rathod 2019-12-06 00:17:31 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`
