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.

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.

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 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 26 Jonathan Christison 2020-02-28 14:59:03 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`
