CVE-2020-36180 is an unsafe deserialization vulnerability in FasterXML Jackson Databind affecting 2.x releases before 2.9.10.8. Jackson Databind mishandles the interaction between polymorphic typing and serialization gadgets associated with the Apache Commons DBCP2 DriverAdapterCPDS class. An application that deserializes attacker-controlled data with vulnerable polymorphic typing configuration can instantiate the gadget class during deserialization.

This repository is a Java proof-of-concept exploit demonstrating unsafe deserialization in the Jackson-databind library (version 2.9.10.7). The main exploit logic is in src/main/java/org/example/POC.java, which crafts a malicious JSON payload that, when deserialized with Jackson's default typing enabled, instantiates the org.apache.commons.dbcp2.cpdsadapter.DriverAdapterCPDS class. The payload's configuration causes the H2 database driver to execute a remote SQL script via the RUNSCRIPT feature, fetching it from http://127.0.0.1:3333/exec.sql. The repository includes a Maven build file (pom.xml) specifying the required dependencies (jackson-databind, commons-dbcp2, h2, etc.), and standard IDE configuration files. The exploit demonstrates how an attacker can achieve remote code execution or database manipulation on a vulnerable Java application that deserializes untrusted data with Jackson-databind and has the relevant classes on the classpath.
