Описание
A deserialization flaw was discovered in the jackson-databind, versions before 2.6.7.1, 2.7.9.1 and 2.8.9, which could allow an unauthenticated user to perform code execution by sending the maliciously crafted input to the readValue method of the ObjectMapper.

Отчет
This issue affects the versions of jackson-databind (in Satellite 6.0 and 6.1) and candlepin (which embeds a copy of jackson-databind in Satellite 6.2) as shipped with Red Hat Satellite 6.x. However the affected code is NOT used at this time: Candlepin currently uses the default type resolution configuration for the ObjectMappers it creates/uses. Nowhere in candlepin do we enable global polymorphic deserialization via enableDefaultTyping(...), therefore based on the documentation sited BZ 1462702 , candlepin should not be affected. However as the vulnerable software ships with the product we have marked them as vulnerable to ensure the issue is tracked. JBoss EAP 7.x only uses the vulnerable Jackson Databind library for marshalling and unmarshalling of JSON objects passed to JAX-RS webservices. Some advise about how to remain safe when using JAX-RS webservices on JBoss EAP 7.x is available here: https://access.redhat.com/solutions/3279231 Although JBoss Fuse ships the vulnerable version of jackson-databind, it does not call on enableDefaultTyping() for any polymorphic deserialization operations which is the root cause of this vulnerability. We have raised a Jira tracker to ensure that jackson-databind will be upgraded for Fuse 7.0, however due to feasibility issues jackson-databind cannot be upgraded in JBoss Fuse 6.3.
Меры по смягчению последствий
Mitigation to this problem is to not trigger polymorphic desrialization globally by using: objectMapper.enableDefaultTyping() and rather use @JsonTypeInfo on the class property to explicitly define the type information.
