Title: Jboss EAP Deserialization of Untrusted Data Vulnerability

Overview:

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.
