Mercedes-Benz XENTRY TIPS Mobile User Impersonation

Type: Security issue, report
Reported to vendor: September 7, 2021
Public disclosure: January 31, 2022

XENTRY TIPS is a database of topics that Mercedes-Benz maintains to help their dealers troubleshoot and fix issues with Mercedes-Benz vehicles. A mobile website built using Angular exists that allows dealer personnel easier access through their mobile devices. The content is locked behind a paid subscription linked to your account, but it was discovered that user impersonation was possible by modifying the user ID value that was sent via query param to their API. If you substituted your user ID with a user ID that had an active subscription (easy to find at the bottom of various TIPS documents posted on the NHTSA website), it was possible to access topics and other resources. The incident was responsibly disclosed to Mercedes-Benz and fixed a few weeks later.
