Amazon ECS Security Alert: Upgrade Now or Risk Server Snooping!
Amazon ECS agent has a bug that could lead to unwanted introspection, like a nosy neighbor peeking through your window! If you’re running ECS Agent versions 0.0.3 through 1.97.0, update to 1.97.1 pronto or tighten your security groups. Remember, introspection is best left to philosophers, not containers!
Hot Take:
Amazon ECS: Keeping us on our toes with container conundrums! Who knew the introspection API could be so introspective that it decided to share its thoughts a bit too openly? It’s time to patch up those containers before they spill the beans!
Key Points:
- Amazon ECS was hit by a vulnerability (CVE-2025-9039) affecting its agent.
- The issue allows off-host access to the introspection server under specific conditions.
- Instances in the same security group or with permissive security group settings are at risk.
- Resolution involves upgrading to ECS Agent version 1.97.1.
- As a workaround, restrict incoming access to port 51678 via security groups.
