Fixed In Version: jackson-databind 2.9.7, jackson-databind 2.7.9.5, jackson-databind 2.8.11.3
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 slf4j, flex messaging, sun DRSHelper and JAX-WS gadgets 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 Laura Pardo 2019-01-15 18:54:51 UTC 
FasterXML jackson-databind 2.x before 2.9.7 might allow attackers to conduct external XML entity (XXE) attacks by leveraging failure to block some JDK classes from polymorphic deserialization.

Comment 1 Laura Pardo 2019-01-15 18:55:25 UTC 
Created jackson-databind tracking bugs for this issue:

Affects: fedora-all [bug 1666424]
Comment 9 Doran Moppert 2019-02-08 05:34:11 UTC 
Statement:

Red Hat Satellite 6 is not affected by this issue, since its only supported Java runtime (openJDK) doesn't bundle the com.sun.deploy.security.ruleset.DRSHelper class.

Red Hat Enterprise Virtualization 4 is not affected by this issue, since its only supported Java runtime (openJDK) doesn't bundle the com.sun.deploy.security.ruleset.DRSHelper class.
Comment 10 James Hebden 2019-02-14 05:23:19 UTC 
OpenDaylight is installed with the OpenJDK JRE, and as such, the JRE does not include the vulnerable class. In addition, the vulnerable class is not used by OpenDaylight, even though jackson-databind is included by the OpenDaylight-parent aggregator at vulnerable versions. I will still create Moderate priority trackers to get the library updated.

Comment 40 Jonathan Christison 2020-02-28 14:23:07 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`
