This benign page is served on skydesperados-poc.docs.ems.eos.comcast.com — a
*.comcast.com host — over a GitHub-issued valid TLS certificate, from a repository
controlled by the researcher.
It demonstrates that the dangling wildcard DNS record *.docs.ems.eos.comcast.com → entos-ems.github.io
allows an arbitrary party to publish content on Comcast subdomains.
No Comcast data was accessed, modified, or impacted. This page will be removed on request.
Reported to Comcast via Bugcrowd. Remediation: remove/scope the wildcard DNS, reclaim unclaimed hosts, verify comcast.com at GitHub org level.
