In this chapter, we saw how compromising a simple containerized CMS led to access to another container, which eventually resulted in full compromise of the host. This is not to say that Docker and container technology should be avoided, but just like any other software, Docker must be configured securely before deployment. A vulnerable or improperly configured container could allow attackers to pivot to other more sensitive applications, or worse...
