Fixed In Version: jackson-databind-2.9.10.2
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 Guilherme de Almeida Suckevicz 2020-01-20 20:02:19 UTC 
FasterXML jackson-databind 2.x before 2.9.10.2 lacks certain net.sf.ehcache blocking.

Comment 1 Fabio Valentini 2020-01-20 22:48:45 UTC 
fedora seems to be not affected by this, as we have jackson-databind 2.10.1 in fedora 30, 31, and rawhide:

Comment 4 Jason Shepherd 2020-01-22 04:09:44 UTC 
Statement:

While OpenShift Container Platform's elasticsearch plugins do ship the vulnerable component, it doesn't do any of the unsafe things described in https://access.redhat.com/solutions/3279231. We may update the jackson-databind dependency in a future release.
Comment 8 Jason Shepherd 2020-02-06 03:20:27 UTC

Comment 14 Eric Christensen 2020-03-04 20:46:07 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`
