CVE-2024-28823Public exploitNetwork attack vector

User-context script execution via unescaped bucket name

Published Mar 11, 2024 · Updated Nov 1, 2024

Cross-site scripting in Amazon AWS JavaScript S3 Explorer 1.0.0 allows remote attackers to execute script via a crafted bucket name. The settings prompt assigned its result directly to s3exp_config.Bucket without htmlEscape, allowing markup to reach the page's HTML rendering path. Exploitation requires a user to submit the crafted name, and injected script runs in that user's browser context.
