GeoServer/JAI-EXT Jiffle (Janino) code injection RCE
JAI-EXT jt-jiffle (used downstream by GeoServer) allows code injection when an application accepts untrusted Jiffle scripts (e.g., via network requests). Jiffle scripts are translated into Java source and then compiled/executed via the Janino compiler; insufficient restriction of what can be emitted into the generated Java enables an attacker to inject malicious Java constructs and reach dangerous APIs (e.g., java.lang.Runtime.getRuntime().exec), resulting in remote code execution in affected GeoServer configurations.

This repository provides a Python exploit script (CVE-2022-24816.py) targeting the GeoServer software vulnerable to CVE-2022-24816, a remote code execution (RCE) vulnerability. The exploit works by sending a specially crafted XML payload to the /geoserver/wms endpoint, abusing the WPS Execute functionality to inject Java code that executes arbitrary system commands on the server. The script takes two arguments: the target GeoServer URL and the command to execute. It processes the server's XML response to extract and display the output of the executed command. The repository includes a README with usage instructions, a requirements.txt listing Python dependencies (requests, urllib3, colorama), and a LICENSE file. The exploit is operational, allowing attackers to run arbitrary commands on vulnerable GeoServer instances accessible over the network.
