CVE-2020-9548 is an unsafe deserialization vulnerability in FasterXML jackson-databind 2.x before 2.9.10.4. Jackson Databind mishandles the interaction between serialization gadgets and typing; the affected gadget is br.com.anteros.dbcp.AnterosDBCPConfig in anteros-core. An attacker may abuse a suitable gadget chain when an application exposes an unsafe polymorphic deserialization path.

This repository contains a proof-of-concept (POC) exploit for CVE-2020-9548, a remote code execution vulnerability in the FasterXML/jackson-databind Java library. The main file, Poc.java, demonstrates how a specially crafted JSON payload can be deserialized using Jackson's ObjectMapper with default typing enabled. The payload references the 'br.com.anteros.dbcp.AnterosDBCPConfig' class and includes an LDAP URL (ldap://localhost:1389/Exploit) as a property, which is a common technique for triggering remote code execution via JNDI lookups. The exploit does not include a malicious LDAP server but shows how the vulnerability can be triggered. The repository structure is simple, with one Java file containing the exploit code and a README describing the vulnerability.
