Key Points / Summary
VE Commercial Vehicles, a joint venture between the Volvo Group and Eicher Motors, builds and maintains a fleet management system called My Eicher for Indian commercial vehicle customers. “My Eicher is a complete fleet management & vehicle GPS tracking system designed for commercial vehicle owners, fleet managers, & operators. With our highly advanced telematics platform, you can take control of your fleet like never before.”
A vulnerability was found in the APIs that made it possible to discover hidden, unauthenticated internal/admin APIs. These APIs could be used to gain high-level access to systems and even enable account takeover.
Account takeover made it possible to gain control over a person’s (or company’s) entire fleet, which could consist of hundreds of vehicles.

It is unclear why some of these numbers pulled from the API are significantly higher. 748k customers 174k users 186k persons 676k vehicles 76k documents (Aadhaar cards, driving licenses, etc)

It wasn’t until more than a year later in 2025 that I stumbled upon a breakthrough that cracked My Eicher wide open.
