CVE-2019-17531: Improper Input Validation

October 12, 2019 (updated October 24, 2019)

A Polymorphic Typing issue was discovered in FasterXML jackson-databind. When Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint and the service has the apache-log4j-extra in the classpath, and an attacker can provide a JNDI service to access, it is possible to make the service execute a malicious payload.
