CVE-2020-9496 is a critical vulnerability in Apache OFBiz (prior to 17.12.04 and 18.12.01) that allows pre-authentication remote code execution via unsafe deserialization of XMLRPC arguments. The /webtools/control/xmlrpc endpoint processes serialized arguments before authentication, enabling attackers to send crafted XML payloads that trigger deserialization in the org.apache.xmlrpc.parser.SerializableParser#getResult method. If suitable gadget classes are present in the classpath, arbitrary code execution is possible with the privileges of the servlet container. The vulnerability was reported by Alvaro Muñoz of the GitHub Security Lab and fixed in July 2020.

This repository contains a Bash exploit script (cve-2020-9496.sh) and a README for CVE-2020-9496, a remote code execution vulnerability in Apache OFBiz 17.12.01 due to unsafe Java deserialization in the /webtools/control/xmlrpc endpoint. The exploit works by generating a malicious serialized Java payload using ysoserial, which is sent to the vulnerable endpoint via a crafted XML-RPC request. The payload instructs the target to download a shell script from the attacker's HTTP server and execute it, resulting in a reverse shell connection back to the attacker's netcat listener. The README provides clear usage instructions, including setting up the attacker's HTTP server and netcat listener, and modifying the script to target the correct URL and port. The exploit is operational and provides a working reverse shell if the target is vulnerable and accessible. The main fingerprintable endpoints are the vulnerable XML-RPC endpoint on the target, the attacker's HTTP server hosting the shell script, and the file path on the target where the shell script is saved and executed.
