CVE-2019-17531
Published: 12 October 2019
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.
From the Ubuntu Security Team
It was discovered that Jackson Databind incorrectly handled deserialization. An attacker could possibly use this issue to execute arbitrary code or other unspecified impact.
