CWE-636
Not Failing Securely ('Failing Open')
When the product encounters an error condition or failure, its design requires it to fall back to a state that is less secure than other options that are available, such as selecting the weakest encryption algorithm or using the most permissive access control restrictions.

Title
Indian Scout Bobber 2025 Infotainment Digital Round skips PIN entry when WCM is silent at boot
Summary
Incorrect behavior order in the Infotainment / Digital Round display of the Indian Motorcycle Scout Bobber + Tech 2025 model year allows an adjacent-network attacker to bypass the PIN entry screen. The Infotainment uses presence of Wireless Control Module (WCM) traffic during its boot window as a proxy for whether an immobilizer is fitted; if no WCM messages are observed, it skips the PIN entry screen and shows the normal user interface. An attacker who silences the WCM during the boot window — for example via a separately tracked CAN bus-off technique — can present a fully unlocked Infotainment despite the PIN never being entered. Specific timing and protocol details have been withheld pending vendor remediation.
