ASG-Zena Cross Platform Server Enterprise Edition version 4.2.1 contains a vulnerability that allows for Cross Site Scripting (XSS) attacks. The application does not properly sanitize user-supplied input, which can be exploited to inject arbitrary JavaScript code into the context of a user's browser session.

This repository contains a proof-of-concept exploit for Rocket Software's Zena application v4.2.1, targeting CVE-2021-45025 and CVE-2021-45026. The exploit leverages a stored XSS vulnerability in the Zena web configuration interface to achieve remote code execution (RCE). The main exploit script, CookieMonster.py, logs into the Zena web interface using default credentials, injects a malicious JavaScript payload (from payload-js.txt) via a vulnerable endpoint, and waits for a user to trigger the payload by visiting the webconfig page. The JavaScript payload steals authentication cookies, uses them to interact with the backend REST API, enumerates users and agents, creates a new task with an attacker-supplied command, and schedules it for execution on a remote agent. The repository is structured with the main Python exploit script, a JavaScript payload file, and supporting project files. The exploit requires the target to be running the vulnerable Zena version with the web interface accessible and default credentials enabled. The attack chain combines browser-based XSS with backend REST API abuse to achieve RCE.
