Binary.com critical vulnerability to remotely steal users' money
Eight days ago I tweeted about hitting binary.com with a killing vulnerability and since it's fixed and publicly disclosed on HackerOne I decided to write about it here on my blog. In the Thursday bug hunting night like other researchers I decided to have a look at the new published programs on HackerOne so I started to look for some bugs in algolia and binary.com which were the two newest published programs. I found some bugs in both websites , but the most interesting one was a bug in cashier on binary.com. That bug allowed me to login to any user's cashier account by just knowing the user ID. Technical details about the bug can be found here on HackerOne , it's publicly disclosed : https://hackerone.com/reports/98247 Your feedback is highly appreciated.
