TIMELINE Oct 12 Reserved by mitre Oct 12 Published (CNA: mitre) Oct 8 ENRICHED — CVE-2019-17531. Received CVSS 9.8 and CPE data from NVD.
A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.0.0 through 2.9.10. 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 (version 1.2.x) jar in the classpath, and an attacker can provide a JNDI service to access, it is possible to make the service execute a malicious payload.
