polymorphic typing issue allows attacker to read arbitrary local files on the server.
CVE: CVE-2019-12086
Component: jackson-databind
CWE: CWE-502
Severity: Moderate
CVSS v3: 7.5/CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Release date: 2019-05-14T00:00:00+00:00

A flaw was discovered in FasterXML jackson-databind, where it would permit polymorphic deserialization of malicious objects using the mysql 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 read arbitrary local files

Statement: Red Hat 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.

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`
