Top Three Interesting Bugs

Shopify is dedicated to publicly disclosing all vulnerability reports discovered through our program to propel industry education and we strongly encourage other companies to do the same. Three of our most interesting resolved bugs over the years are:

1. SSRF in Exchange leads to ROOT access in all instances - Bounty: $25,000 

Shopify infrastructure is isolated into subsets of infrastructure. @0xacb reported it was possible to gain root access to any container in one particular subset by exploiting a server-side request forgery bug in the screenshotting functionality of Shopify Exchange. Within an hour of receiving the report, we disabled the vulnerable service, began auditing applications in all subsets and remediating across all our infrastructure. The vulnerable subset did not include Shopify core. After auditing all services, we fixed the bug by deploying a metadata concealment proxy to disable access to metadata information. We also disabled access to internal IPs on all infrastructure subsets.

2. Shopify admin authentication bypass using - Bounty: $20,000

@uzsunny reported that by creating two partner accounts sharing the same business email, it was possible to be granted “collaborator” access to a store. We tracked down the bug to incorrect logic in a piece of code that was meant to automatically convert an existing normal user account into a collaborator account. The intention was that, when a partner had a valid user account on the store, their collaborator account request could be accepted automatically, with the user account converted into a collaborator account. We fixed this issue by properly verifying that the existing account is in fact a user account.

3. Stored cross site scripting in Shopify admin and partner pages - Bounty $5,000

@bored-engineer found we were incorrectly sanitizing sales channel icon SVG files uploaded by Partner accounts. During our remediation, we noted the XSS would execute in and the Shopify admin panel, which increased the impact of this bug. The admin functionality was not required, so it was removed. Additionally, we verified that the bug had not been exploited by any other users.

Having reached the $1M in awarded bounties, we’re still looking for ways to ensure our program remains competitive and attractive to hackers. This year we’ll be experimenting with new ways to drive hacker engagement and make Shopify’s bug bounty program more lucrative and attractive to hack on.

Happy Hacking!
