WebLogic Deserialization of Untrusted Data Vulnerability - CVE-2019-16942

Critical
Reference: CVE-2019-16942
NVD Link: https://nvd.nist.gov/vuln/detail/CVE-2019-16942
Title: WebLogic Deserialization of Untrusted Data Vulnerability
Overview:

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 commons-dbcp (1.4) jar in the classpath and an attacker can find an RMI service endpoint to access it is possible to make the service execute a malicious payload. This issue exists because of org.apache.commons.dbcp.datasources.SharedPoolDataSource and org.apache.commons.dbcp.datasources.PerUserPoolDataSource mishandling.
