The Paranoids


EdgeCast CDN

Verizon Digital Media Services' EdgeCast Content Delivery Network has a capacity of 50+ Tbps and 125 points of presence (PoPs) spanning 56 countries across six continents. A network connected with over 3,000 carriers and ISPs, we not only strive to be the fastest and most reliable Content Distribution Network (CDN), but also the most secure.

Our CDN partners configure their accounts and manage their own customers using either the Partner Control Center (PCC) or API. This is where we ask you to help us ensure that our partners' account settings and data are safe and secure.

Known Issues

There are a number of notable known issues on this product that should not be reported (and are not eligible for bounty), to prevent duplicates, some of the most visible ones include:

  • An attacker can access a feature/endpoint that he or she does not have access to if the URL is known. The root cause is an Insecure Direct Object Reference (IDOR) issue.
