How i got $15000 Reward by Apple - Information Disclosure

                          

It's been quite long time i wrote a blog, Today i would like to disclose one of my findings in Apple which was reported via Apple bug bounty program.

While browsing through the Apple subdomains i came across a subdomain which is a tool used by Apple and it's customers.

After login to the tool and going through the application, i came across different vulnerable endpoints where changing the id (which was numeric value) led me to information disclosure (email address) such as @apple.com , @bbc.com and other customers email addresses . I was able to fetch millions of email addresses using this vulnerability.


Below are few of the screenshots where data was leaking.

Apple was quick in fixing these issues, they rewarded total $15000 USD .

 

 

 

 That's all for today, will disclose more writeups in future :)

Thanks
