This Mitiga blog provides a concise operational playbook to find and test external-facing AWS workloads for the Log4Shell Log4j vulnerabilities (CVE-2021-44228 and CVE-2021-45046). It details required IAM permissions, how to enumerate public EC2 instances and load balancer URLs, configuring an out‑of‑band interaction proxy, executing a proof‑of‑concept exploit to detect RCE, and documenting resources for remediation.
