ASVS 5.0
V15 - Secure Coding and Architecture Incorrect behavior order
|
| Exploitation Conditions | Exploitation requires physical access to the motorcycle's CAN bus (e.g., via the OBD/diagnostic port or a direct bus tap) during a specific startup boot window - the duration and exact timing of this window have been withheld by ASRG pending vendor remediation. The PIN bypass is only meaningful if the vehicle owner has configured PIN protection on the infotainment system; vehicles without PIN protection enabled are not affected by this logic flaw. The CVSS AV:P vector confirms physical access as the baseline requirement, though the description's use of 'adjacent-network attacker' language introduces ambiguity about whether wireless WCM silencing at close range is feasible - this is unconfirmed and represents the key open question for risk assessment. Exploitation is scoped to the 2025 model year Scout Bobber + Tech; no other models are cited. The low CVSS confidentiality impact (C:L) indicates that what is exposed is the infotainment UI rather than high-sensitivity data or vehicle control systems. |
| Impact | The CVSS 3.1 base score of 2.4 (Low) reflects significant physical constraints: AV:P (Physical access required), AC:L (Low attack complexity), PR:N (no privileges required), UI:N (no user interaction needed), with impact limited to C:L (Low confidentiality) and no integrity or availability impact. A material discrepancy exists between the CVE description's characterization of an 'adjacent-network attacker' and the CVSS AV:P (Physical) designation - if WCM silencing is achievable wirelessly at adjacent range rather than requiring direct CAN bus access, the attack vector classification should be AV:A, which would meaningfully change exposure. This should be verified with ASRG or Indian Motorcycle before making access-vector-dependent risk decisions. No EPSS score was provided in the available data. The vulnerability is not listed in CISA KEV, and no public exploit code exists. Real-world risk is further constrained by the requirement to operate during a specific startup boot window, the limited scope to the 2025 model year, and the low confidentiality impact of exposing the infotainment UI. This is a low-priority finding for enterprise security teams but relevant for automotive security practitioners and vehicle owners concerned with unauthorized physical access scenarios. |
| Exploit ScenarioDerived | An attacker with access to the motorcycle's CAN bus - obtained via the OBD diagnostic port or a direct bus tap - initiates a CAN bus-off attack targeting the Wireless Control Module during the infotainment's startup boot window, suppressing all WCM messages. The infotainment interprets the absence of WCM traffic as evidence that no immobilizer is fitted and skips the PIN entry screen, presenting the fully unlocked user interface. No public exploit code exists for this specific scenario, but CAN bus-off is a documented automotive security technique applicable to this attack path. |

Alert meAnalysisAIv1 – May 29, 2026
PIN entry bypass in the Indian Motorcycle Scout Bobber + Tech 2025 infotainment system allows an attacker with physical proximity to the vehicle to access the fully unlocked infotainment interface without entering the correct PIN. The root cause (CWE-696, Incorrect Behavior Order) is that the system treats the presence of Wireless Control Module (WCM) CAN bus traffic during its startup boot window as a proxy for immobilizer detection, and skips PIN enforcement entirely when no WCM messages are observed - a condition an attacker can manufacture by silencing the WCM. Reported by ASRG with no public exploit code and no CISA KEV listing; specific timing and protocol details have been withheld pending vendor remediation.
RemediationAI
No vendor-released patch has been identified at time of analysis. ASRG has withheld specific timing and protocol details pending vendor remediation, indicating that coordinated disclosure with Indian Motorcycle (Polaris Inc.) is active but incomplete. Until a firmware update is released, owners relying on the infotainment PIN feature for vehicle security should avoid leaving the motorcycle unattended during the startup sequence in unsecured locations, as this is the window during which an attacker could interfere with CAN bus traffic - the trade-off is that this control is entirely behavioral and not enforceable. Owners should monitor Indian Motorcycle's official service bulletin and software update channels for remediation firmware. The CWE-696 root cause definition is available at https://cwe.mitre.org/data/definitions/696.html for technical context. If the vendor confirms that WCM silencing is achievable wirelessly at adjacent range, restricting physical proximity to the vehicle during startup would be an additional compensating control.

Technical ContextAI · show details
The affected component is the Infotainment / Digital Round display unit in the Indian Motorcycle Scout Bobber + Tech, 2025 model year, manufactured by Polaris Inc. (CPE: cpe:2.3:a:indian_motorcycle_(polaris_inc.):scout_bobber_+_tech:*:*:*:*:*:*:*:*). The infotainment and Wireless Control Module (WCM) communicate over the vehicle's CAN (Controller Area Network) bus, a broadcast protocol with no native sender authentication. CWE-696 (Incorrect Behavior Order) identifies the root cause: the authentication decision of whether to enforce PIN entry is evaluated based on an observable bus condition - WCM message presence - rather than on a positive, tamper-resistant attestation from the immobilizer subsystem. This inverts secure design principles, making PIN enforcement an opt-in outcome of untrusted bus state rather than a default that requires explicit bypass authorization. A CAN bus-off attack, a documented automotive technique that forces a node off the bus by inducing error conditions, is cited as one method to suppress WCM traffic.

Lifecycle Timeline
1DescriptionCVE.org
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.
