FasterXML jackson-databind <2.9.9.1 - Deserialization

Title source: llm

Exploitation Summary

EIP tracks 4 public exploits for CVE-2019-12384. PoCs published by jas502n, MagicZer0, dawetmaster.

AI-analyzed exploit summary This repository contains a functional exploit for CVE-2019-12384, demonstrating a Jackson deserialization vulnerability leading to RCE via H2 database JDBC URL injection. The PoC uses JRuby to trigger the exploit chain, fetching and executing a malicious SQL script from a remote server.

Description

FasterXML jackson-databind 2.x before 2.9.9.1 might allow attackers to have a variety of impacts by leveraging failure to block the logback-core class from polymorphic deserialization. Depending on the classpath content, remote code execution may be possible.
