Loading vulnerability…
CVE-2023-0297 is a pre-authentication remote code execution vulnerability in pyLoad versions prior to 0.5.0b3.dev31. The vulnerability is due to unsafe use of js2py's eval_js function in the /flash/addcrypted2 endpoint, where user-supplied input (the 'jk' parameter) is evaluated as JavaScript. Because js2py's pyimport functionality is enabled by default, attackers can inject JavaScript that imports and executes arbitrary Python code, including OS commands, without authentication. The vulnerable code is present in cnl_blueprint.py and misc.py.

This repository contains a single Metasploit module (modules/exploits/linux/http/pyload_js2py_exec.rb) targeting a remote code execution vulnerability (CVE-2023-0297) in pyLoad versions prior to 0.5.0b3.dev31. The exploit leverages the js2py 'pyimport' functionality exposed via the /flash/addcrypted2 HTTP endpoint on the 'Click 'N' Load' service (default port 9666), which is accessible without authentication. The module supports multiple payload types, including Unix command execution, Python code execution, and binary droppers, and is weaponized for use within the Metasploit framework. The exploit is network-based and requires the vulnerable service to be exposed. The code is well-structured, with clear separation of payload delivery methods and robust error handling. No hardcoded IPs or domains are present, but the endpoint and port are fingerprintable. The repository is a single Ruby file, typical for Metasploit modules.
This repository contains a Bash script exploit for CVE-2023-0297. The main file, 'CVE-2023-0297.sh', is a command-line tool that takes three arguments: the attacker's host (LHOST), port (LPORT), and the target web application's URL (WEBHOST). The script is designed to exploit a remote code execution vulnerability by sending a crafted POST request to the endpoint '/flash/addcrypted2' on the target server. The payload in the POST data leverages Python's os.system to execute a bash reverse shell, connecting back to the attacker's machine. The script prompts the user to set up a netcat listener before launching the attack. The README is minimal and provides a link to a demonstration asset. The exploit is operational, providing a working reverse shell if the target is vulnerable. No hardcoded IPs or credentials are present; all parameters are supplied by the user at runtime.
