A bug in the McDonald’s Monopoly VIP game in the United Kingdom caused the login names and passwords for the game’s database to be sent to all winners. BleepingComputer reports: After skipping a year due to COVID-19, McDonald’s UK launched their popular Monopoly VIP game on August 25th, where customers can enter codes found on purchase food items for a chance to win a prize. These prizes include 100,000 pounds in cash, an Ibiza villa or UK getaway holiday, Lay-Z Spa hot tubs, and more. Unfortunately, the game hit a snag over the weekend after a bug caused the user name and passwords for both the production and staging database servers to be in prize redemption emails sent to prize winners.
An unredacted screenshot of the email sent to prize winners was shared with BleepingComputer by Troy Hunt that shows an exception error, including sensitive information for the web application. This information included hostnames for Azure SQL databases and the databases’ login names and passwords, as displayed in the redacted email below sent to a Monopoly VIP winner. The prize winner who shared the email with Troy Hunt said that the production server was firewalled off but that they could access the staging server using the included credentials. As these databases may have contained winning prize codes, it could have allowed an unscrupulous person to download unused game codes to claim the prizes. Luckily for McDonald’s, the person responsibly disclosed the issue with McDonald’s, and while they did not receive a response, they later found that the staging server’s password was soon changed.
