At Comcast, we’re committed to working alongside the security research community, and know we’re at our best when we continually enhance this process. That's why we’ve launched Xfinity Home’s bug bounty and expanded the scope to include Xfinity xFi. With your help, we continue with our mission to make Xfinity products more secure.
Xfinity Home is a complete home security system, with 24/7 professional monitoring, and battery/cellular backup. Our customers enjoy peace of mind through live video monitoring with our Xfinity cameras, and motion activated recording that detects people, vehicles, and pets. The door/window sensors allow you to monitor your home and receive real-time alerts when doors are open or closed.
Xfinity xFi gives you the ultimate control of your in-home WiFi from anywhere, on any device. With xFi and an xFi enabled gateway, you can view connected devices, create profiles, pause WiFi to any device, and more. xFi Advanced Security helps keep you safe on sites people visit, prevent remote access from unknown sources, and report/block suspicious device activity with real-time app notifications.
Please note, this program is specifically scoped for Xfinity Home and Xfinity xFi. If you believe you've found a security issue related to any other product or service(or are unsure) please report through our vulnerability disclosure program.
For the initial prioritization/rating of findings, this program will use the Bugcrowd Vulnerability Rating Taxonomy. However, in some cases, a vulnerability priority will be modified due to its attack complexity, requirements, likelihood, or impact of successful exploitation.
All submissions are reviewed to determine an accurate priority and any change will result in a detailed explanation provided to the researcher with the opportunity for a follow up.
Rewards are determined through an internal impact assessment, researcher interaction and the overall quality, content, and accuracy of the report.
High impact findings
Comcast may reward eligible P1 submissions up to $10,000 for findings related to:
Remote unauthorized access (via publicly accessible internet, not on the same LAN/wireless network) of:
- Cloud storage videos
- Live camera feeds
Bypassing Armed Systems
Abuse/Theft of Service
Abuse/Theft of Service
Unauthorized access to WiFi credentials
|VRT Name||Adjusted Priority|
|High Impact Subdomain Takeover||P2 -> P3|
|Basic Subdomain Takeover||P3 -> P4|
|Technical severity||Reward range|
|p1 Critical||$1,500 - $3,500|
|p2 Severe||$750 - $1,200|
|p3 Moderate||$300 - $600|
|p4 Low||Up to: $250|
Out of scope
The following assets are not yet eligible for bounty and should be reported through our vulnerability disclosure program.
|xFi Gateways (e.g., XB3, XB6, XB7)||Hardware|
All submissions must have demonstrable impact on the Xfinity Home or xFi. To be able to test comprehensively, researchers must be a current Xfinity subscriber. Without an active Xfinity account, the available attack surface is highly limited - however, we encourage researchers to test with what is available to them.
All Comcast/Xfinity endpoints called by Xfinity Home/xFi applications are in-scope.
|xhomeapi-*.cloud.comcast.net||API for fetching device information|
|*-cvr-aws-*.sys.comcast.net||Endpoints for CVR data|
|*signalservice.comcast.net||Endpoint for live video|
|api.sc.xfinity.com||API for retrieving user information|
|internet.xfinity.com||Website for xFi functionality|
|siorc.xfinity.com||Endpoint for mobile app orchestration|
|speedtest.xfinity.com||Used to determine Internet speed connection|
|orc-xfi.com||xFi orchestration layer|
|smartinet.xfinity.com||xFi orchestration layer|
|Wireless motion sensors|
|Xfinity Home Cameras|
Out of Scope Details
Any domain/property of Comcast not listed in the targets section is out of scope for this bounty program. This includes any/all subdomains not listed above. If you believe you've identified a Comcast vulnerability on a system outside the scope of this program, please report it through our vulnerability disclosure program.
- Email spoofing issues (e.g., SPF, DKIM, DMARC)
- Automated scan reports without valid proof of concept
- Physical tampering of the device (I/O devices such as USB, SIM, and SD card slots are in scope)
- 3rd party integration
- For a running list, please refer to our Works with Xfinity page.
- Reports requiring a rooted/jailbroken device
- Duplicate/known submissions
- Load Testing (DoS, DDoS, wireless jamming, etc.)
- Social engineering attacks
- Theoretical security issues
- Protocol-specific flaws
Additionally, as an Internet Service Provider, technologies hosted by residential or business customers are considered out-of-scope. These can typically be identified by the FQDN format below.
Researchers must have explicit permission from the account owner to perform any form of security testing.
Researchers may not be a current or former employee, contractor or immediate family member.
Note: This program adheres to Bugcrowd's coordinated disclosure terms. We ask that you provide us a copy of your disclosure report prior to publication and do not publicly report findings until they been fully remediated.
