SELLEST OSAST
Ben and Ryan Show Episode 12
In this episode, your hosts Ben Nadel and Ryan Brown sit down with security expert Brian Riley, author of the HoyaHaxa blog, to discuss ColdFusion security vulnerabilities and best practices for mitigating risks. The conversation dives into recent ColdFusion exploits, how security patches impact developers, and the broader implications of securing applications beyond just ColdFusion itself.
Key Points:
• ColdFusion has been targeted by multiple 0-day vulnerabilities, highlighting its continued presence in critical systems.
• Adobe's recent security updates introduce breaking changes, forcing developers to make necessary adjustments.
• Security is a multi-layered approach—application security is just one part of a larger ecosystem that includes OS, networking, and cloud infrastructure.
• The trade-off between convenience and security often leads to vulnerabilities, especially with features like remote CFC access.
• Managed hosting providers and security tools like HackMyCF can help developers stay ahead of emerging threats.
Discussion Highlights:
ColdFusion Security Landscape
• ColdFusion is still actively targeted by attackers, despite debates over its relevance.
• Government and financial institutions heavily rely on ColdFusion, making it a high-value target.
Adobe's Recent Security Updates
• Adobe is pushing security patches that enforce stricter security measures, sometimes breaking legacy applications.
• The variable scoping issue is a major focus—forcing developers to fix long-standing bad practices.
• Deprecated encryption methods are being phased out for stronger security.
Common Security Best Practices
• Regularly update ColdFusion and all associated components like Java and Tomcat.
• Restrict access to CFIDE and ColdFusion Administrator to prevent common exploits.
• Use a multi-layered defense strategy, including web application firewalls (WAFs), OS-level security, and network protections.
Challenges of Security in Hosting and DevOps
• Managed hosting providers must balance security with not breaking customer applications.
• Attackers often leverage vulnerabilities beyond just the ColdFusion layer, including database, OS, and network weaknesses.
• Cloudflare and similar services help block DDoS attacks but aren't always sufficient in real-time scenarios.
The Convenience vs. Security Tradeoff
• Many vulnerabilities exist because developers prioritize ease of use over security.
• Features like remote CFC access, while convenient, often introduce security risks.
• Security teams and developers must collaborate to strike the right balance between usability and protection.
Final Thoughts and Resources
• Brian Riley's blog HoyaHaxa provides deep dives into ColdFusion security issues.
• OWASP’s Top Ten is a great resource for understanding common security vulnerabilities.
• Developers should engage in proactive security practices rather than waiting for the next 0-day exploit.
