Security: S3 Bucket Sniping Vulnerability in Documentation

Summary

Documentation contains example S3 bucket names that could be claimed by attackers, creating a bucket sniping vulnerability.

Severity

Medium - Documentation issue that could lead users to reference attacker-controlled resources.

Vulnerability Details

The custom-bootstrap.markdown documentation files across all versions contain hardcoded example values that appear realistic:

  • Bucket: ddk-abcdefgh-assets-000000000000-us-west-2
  • Account ID: 000000000000
  • Qualifier: abcdefgh
  • Region: us-west-2

These values could be claimed by malicious actors, potentially allowing them to serve malicious content to users who copy examples directly.

Impact

  • Users copying examples verbatim could reference attacker-controlled S3 buckets
  • Potential for supply chain attacks if malicious assets are served
  • Confusion between example and production resources

Solution

Replace all hardcoded values with clearly marked placeholders:

  • ddk-<QUALIFIER>-assets-<YOUR-ACCOUNT-ID>-<REGION>
  • <YOUR-ACCOUNT-ID> instead of 000000000000
  • <QUALIFIER> instead of abcdefgh
  • <REGION> instead of us-west-2

Files Affected

  • docs/release/*/how-to/custom-bootstrap.markdown (all versions)
  • test/base-stack.test.ts

Fix Status

✅ Fixed in branch: fix/update-doc-sec-vulnerability

  • All documentation updated with placeholder format
  • Test files updated with safe, unclaimed test values
  • All unit tests passing (14/14)

References

  • Related to bucket sniping attacks on public documentation
  • Similar to dependency confusion attacks

Replace hardcoded example S3 bucket names and AWS resource identifiers
with clearly marked placeholders to prevent bucket sniping attacks.

Add archive notice to README indicating the repository is no longer
maintained and has been made read-only for historical reference.

Changes:
- Replace 'ddk-abcdefgh-assets-000000000000-us-west-2' with
  'ddk-<QUALIFIER>-assets-<YOUR-ACCOUNT-ID>-<REGION>'
- Replace hardcoded account ID '000000000000' with '<YOUR-ACCOUNT-ID>'
- Replace hardcoded region 'us-west-2' with '<REGION>'
- Replace hardcoded qualifier 'abcdefgh' with '<QUALIFIER>'
- Update all IAM role ARNs to use placeholder format
- Update test fixtures to use safe, unclaimed test values
- Add archive warning banner to README.md

Impact:
- Prevents attackers from claiming example bucket names
- Makes it obvious these are placeholder values requiring replacement
- Clearly communicates repository archive status to users
- All unit tests continue to pass (14/14)

Files modified:
- docs/release/*/how-to/custom-bootstrap.markdown (all versions)
- test/base-stack.test.ts
- README.md
