AWS Ansible Misconfiguration: Improper EC2 Network Access Control

YAML

Abstract

Uma tarefa Ansible define um Grupo de segurança AWS com permissões de acesso excessivamente amplas.

Explanation

As configurações de acesso livre expõem os sistemas desnecessariamente e ampliam a superfície de ataque de uma organização. Os serviços abertos à interação com o público são normalmente submetidos a varreduras e investigações quase contínuas por entidades mal-intencionadas.

Isso é especialmente problemático quando um exploit de dia zero para um serviço exposto é descoberto e publicado (por exemplo, Heartbleed). Os invasores podem perseguir e pesquisar ativamente sistemas não corrigidos e expostos para explorá-los.

Exemplo 1: A seguinte tarefa Ansible define um Grupo de segurança AWS que abre para o mundo (0.0.0.0/0 ) a porta TCP 22 , onde um servidor SSH normalmente responde às solicitações de conexão de entrada.


- name: Task to open SSH port
  amazon.aws.ec2_group:
    name: demo_security_group
    description: Open the ssh port to the world
    state: present
    vpc_id: 123456
    region: us-west-1
    rules:
    - proto: tcp
        ports: 22
        cidr_ip: 0.0.0.0/0
