CVE-2026-49318: CWE-696 Incorrect Behavior Order in Indian Motorcycle Scout Bobber + Tech
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.
AI Analysis
Technical Summary
CVE-2026-49318 describes a logic flaw in the 2025 Indian Motorcycle Scout Bobber + Tech infotainment system where the presence of Wireless Control Module (WCM) traffic during boot is used as a proxy to determine if an immobilizer is installed. If WCM traffic is absent, the system bypasses the PIN entry screen and grants access to the normal user interface. An attacker on an adjacent network can silence the WCM during the boot window, such as by inducing a CAN bus-off condition, thereby bypassing the PIN requirement and unlocking the infotainment system without authentication. The vulnerability is classified under CWE-696 (Incorrect Behavior Order). No patch or official remediation has been disclosed yet.
Potential Impact
The vulnerability allows an adjacent-network attacker to bypass the PIN entry screen of the infotainment system, potentially granting unauthorized access to the system's normal user interface. The CVSS score is low (2.4) with low confidentiality impact, no integrity or availability impact, and requires physical proximity (adjacent network). There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, monitoring for abnormal CAN bus behavior or attempts to silence the Wireless Control Module during boot may help detect exploitation attempts. No official fix or temporary mitigation has been published by the vendor.
