hi, i’m daniel. i’m a 15-year-old with some programming experience and i do a little bug hunting in my free time. here’s the insane story of how I found a single bug that affected over half of all Fortune 500 companies:
They absolutely can and should fix it, but in the end, IMHO, it’s a mail server misconfiguration coupled with a slack issue, not a Zendesk security issue
I can see both angles of this. Especially since the original disclosure didn’t have the full detail of how it could be exploited to access company systems, and they (the writeup author) never disclosed that update.
You can see how a large company (Zendesk) could miss this in the multitude of people trying to claim bug bounties. I fully believe that had they understood the issue they should have fixed it, since it’s within their power and basically a service to their clients. But I can understand how the limited detail in the original disclosure demonstrated a much lower level risk than the end exploit that was never reported.
Nah, zendesk should absolutely have recognised that gaining unauthorised read access to support ticket email chains is a massive security issue. Firstly “support email chains” accounts for proportionately nearly all the data zendesk is handling, so a vulnerability there is core to the product, not at all peripheral, and secondly, who on earth is working in tech today that doesn’t know that your email is they key to all your online accounts?
Zendesk here were blatantly either stupid or in denial and treated a bug reporter as a low life enemy instead of an asset. The kid did right by any plausible moral viewpoint.
