The presentation discusses the importance of cybersecurity in DevOps and highlights the vulnerabilities in reverse proxy architecture and URL path parameters.
- Reverse proxy architecture can be vulnerable to attacks that bypass security controls
- URL path parameters can lead to security problems due to differences in implementation between web servers
- Proper isolation of backend applications and ensuring behavior between proxy and backend servers can prevent attacks
- Thin features in frameworks like Struts can introduce dangerous expression language that must be carefully controlled
During a code review of an open source content management system, the presenter found several tiny bugs that could be chained together to gain unauthorized access. The system was based on the Struts framework, which introduced dangerous expression language that had to be carefully controlled.
