Peloton’s leaky API let anyone grab rider’s private account data – TechCrunch

Posted on

Midway via my Monday afternoon exercise final week, I bought a message from a security researcher with a screenshot of my Peloton account data.

My Peloton profile is about to private and my good friend’s checklist is intentionally zero, so no person can view my profile, age, metropolis, or exercise historical past. However a bug allowed anyone to drag customers’ private account data straight from Peloton’s servers, even with their profile set to private.

Peloton, the at-home health model synonymous with its indoor stationary bike, has greater than three million subscribers. Even President Biden is even said to own one. The train bike alone prices upwards of $1,800, however anyone can join a month-to-month subscription to affix a broad number of lessons.

As Biden was inaugurated (and his Peloton moved to the White Home — assuming the Secret Service let him), Jan Masters, a security researcher at Pen Check Companions, discovered he might make unauthenticated requests to Peloton’s API for person account data with out it checking to verify the particular person was allowed to request it. (An API permits two issues to speak to one another over the web, like a Peloton bike and the corporate’s servers storing person data.)

However the uncovered API let him — and anyone else on the web — entry a Peloton person’s age, gender, metropolis, weight, exercise statistics, and if it was the person’s birthday, particulars which might be hidden when customers’ profile pages are set to private.

Masters reported the leaky API to Peloton on January 20 with a 90-day deadline to repair the bug, the usual window time that security researchers give to firms to repair bugs earlier than particulars are made public.

However that deadline got here and went, the bug wasn’t mounted, and Masters hadn’t heard again from the corporate, except for an preliminary e-mail acknowledging receipt of the bug report. As a substitute, Peloton solely restricted entry to its API to its members. However that simply meant anyone might join with a month-to-month membership and get entry to the API once more.

TechCrunch contacted Peloton after the deadline lapsed to ask why the vulnerability report had been ignored, and Peloton confirmed yesterday that it had mounted the vulnerability. (TechCrunch held this story till the bug was mounted with the intention to stop misuse.)

Peloton spokesperson Amelise Lane offered the next assertion:

It’s a precedence for Peloton to maintain our platform safe and we’re all the time trying to enhance our strategy and course of for working with the external security neighborhood. Via our Coordinated Vulnerability Disclosure program, a security researcher knowledgeable us that he was in a position to entry our API and see data that’s accessible on a Peloton profile. We took action, and addressed the problems primarily based on his preliminary submissions, however we had been sluggish to replace the researcher about our remediation efforts. Going ahead, we are going to do higher to work collaboratively with the security analysis neighborhood and reply extra promptly when vulnerabilities are reported. We wish to thank Ken Munro for submitting his stories via our CVD program and for being open to working with us to resolve these points.

Masters has since put up a blog post explaining the vulnerabilities in additional element.

Munro, who based Pen Check Companions, advised TechCrunch: “Peloton had a little bit of a fail in responding to the vulnerability report, however after a nudge in the proper path, took acceptable action. A vulnerability disclosure program isn’t only a web page on an internet site; it requires coordinated action throughout the organisation.”

However questions stay for Peloton. When requested repeatedly, the corporate declined to say why it had not responded to Masters’ vulnerability report. It’s additionally not identified if anyone maliciously exploited the vulnerabilities, resembling mass-scraping account data.

Fb, LinkedIn, and Clubhouse have all fallen victim to scraping attacks that abuse entry to APIs to drag in data about customers on their platforms. However Peloton declined to verify if it had logs to rule out any malicious exploitation of its leaky API.
