Exploitation Summary
EIP tracks 4 public exploits for CVE-2019-12086. PoCs published by Al1ex, motoyasu-saburi, dawetmaster.
AI-analyzed exploit summary This repository contains a functional exploit for CVE-2019-12086, a deserialization vulnerability in Jackson. The PoC demonstrates how an attacker can craft a malicious JSON payload to trigger an LDAP or JDBC connection to a rogue server, leading to information leakage or remote code execution.
Description
A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.x before 2.9.9. When Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint, the service has the mysql-connector-java jar (8.0.14 or earlier) in the classpath, and an attacker can host a crafted MySQL server reachable by the victim, an attacker can send a crafted JSON message that allows them to read arbitrary local files on the server. This occurs because of missing com.mysql.cj.jdbc.admin.MiniAdmin validation.

This repository contains a functional PoC for CVE-2019-12086, demonstrating arbitrary file read via Jackson Databind deserialization with MySQL JDBC connector. The exploit leverages polymorphic typing to trigger a connection to a malicious MySQL server, which then exfiltrates local files.
This repository contains a vulnerable version of Jackson Databind (2.9.0) that is susceptible to CVE-2019-12086, a deserialization vulnerability. The included source code and build configuration allow for testing and exploitation of the flaw.
