NVD Description

Note: Versions mentioned in the description apply only to the upstream eap7-wildfly package and not the eap7-wildfly package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

A flaw was discovered in FasterXML jackson-databind in all versions before 2.9.10 and 2.10.0, where it would permit polymorphic deserialization of malicious objects using the xalan JNDI 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.
