AWS Deployment Framework Flaw: Upgrade Now or Face the Chaos
AWS Deployment Framework users: Upgrade to version 4.0+ to fix CVE-2024-37293 and mitigate privilege escalation risks. Temporary fix: add a permissions boundary in the management account. Thanks to Xidian University for the responsible disclosure.
Hot Take:
Looks like AWS just revealed their Achilles’ heel in the form of a bootstrap process that’s more like a bootstrapped rollercoaster! If you’re not on version 4.0, it’s time to upgrade faster than your morning coffee kicks in. Thanks, Xidian University, for being the Gandalf to AWS’s Frodo in this cybersecurity saga.
Key Points:
- CVE-2024-37293 impacts the AWS Deployment Framework (ADF) bootstrap process.
- Two vulnerable versions: CodeBuild-driven and Lambda-driven bootstrap processes.
- Potential for privilege escalation if actors alter CodeBuild projects or Lambda functions.
- Issue addressed in ADF version 4.0 and above – upgrade ASAP!
- Temporary mitigation: Apply a permissions boundary to deny IAM and STS actions.
