C. Papathanasiou 2010

INTRODUCCIÓN

Este script de JBoss implementa un shell JSP en el servidor JBoss AS objetivo. Una vez implementado, el script utiliza su capacidad de carga y ejecución de comandos para proporcionar una sesión interactiva.

Las características incluyen:

Soporte multiplataforma – probado en objetivos Windows, Linux y Mac
Soporte para shells bind y reverse bind
Shells Meterpreter y soporte VNC para objetivos Windows

INSTALACIÓN

Las dependencias incluyen:

Netcat
Curl
Metasploit v3, instalado en la ruta actual como "framework3"

USO

Use e.sh para objetivos *nix que utilicen bind_tcp y reverse_tcp

./e.sh target_ip tcp_port

Use e2.sh para objetivos Windows que puedan ejecutar payloads de Metasploit para Windows

./e2.sh target_ip tcp_port
