The broker Access Control vulnerability in the API Endpoint of the app gave unauthorised access for attackers to modify data.

The API Endpoint was vulnerable to Broken Access Control vulnerability. On accessing my profile section within the application, a POST request was sent to the backend server with my user id, deviceID and Base64 encoded access_token.” said the researcher to GBHackers.

The vulnerability allowed the attacker to view and access:

  1. Personal data of every Indane LPG customers and modify it
  2. Distributors bank details
  3. Access online order history of customers
  4. Book a new LPG cylinder
  5. Make changes on subsidy request without user consent

The distributor’s bank details exposed includes name, bank name, account number, IFSC code, email and the phone number linked with the bank account.

The researcher was able to access information about other indane consumers by modifying the value of “userid” incrementally.
