Exploitation Conditions

Exploitation requires direct, hands-on physical access to the 2025 Indian Motorcycle Scout Bobber + Tech's Wireless Control Module wiring harness - confirmed by CVSS AV:P. In practice this means the attacker must be able to remove or bypass body panels protecting the harness and then disconnect or cut the specific wire pair used by the WCM to signal shutdown to the peer ECU. The CVSS PR:N vector confirms no authentication credential or account access is needed once physical access is obtained. Limiting factors are significant: no remote, adjacent-network, or local software exploitation path exists; the attack is bounded to in-person access to the parked vehicle; and ASRG has withheld the specific connector identity pending vendor remediation, temporarily raising the technical knowledge bar. Non-default configuration, software settings, or network connectivity play no role in triggering this vulnerability.

Impact

The CVSS 4.6 (Medium) score is appropriate and principally deflated by AV:P (physical attack vector), which mandates hands-on access to the wiring harness - eliminating all remote and network-based exploitation paths. AC:L confirms the manipulation requires no specialized electronic skills once physical access is achieved, and PR:N reflects that no credentials are needed to execute the bypass. The A:H impact captures full defeat of the anti-theft immobilizer. No EPSS score was included in the provided intelligence, so probabilistic exploitation likelihood cannot be quantified. KEV status is not confirmed; no public proof-of-concept code has been identified at time of analysis. Real-world risk is bounded to targeted physical theft scenarios - a thief who can reach the harness. This is a meaningful risk for vehicle owners but not a mass-exploitation concern. The ASRG decision to withhold specific connector locations temporarily raises the bar for replication.

Exploit ScenarioDerived

A thief approaches a parked 2025 Indian Motorcycle Scout Bobber + Tech, removes one or more body panels to expose the WCM wiring harness connector, and physically disconnects or cuts the dedicated shutdown signal wire pair - an action requiring basic hand tools and no electronic equipment. The receiving ECU, unable to distinguish this open-circuit condition from a valid operational state, releases the immobilizer and allows the engine to start and the motorcycle to be ridden away without any PIN entry. No public proof-of-concept code exists, but the attack requires only physical access and knowledge of the relevant connector location.

AnalysisAIv1 – May 29, 2026

Anti-theft bypass in the 2025 Indian Motorcycle Scout Bobber + Tech allows a physical attacker who can access the Wireless Control Module wiring harness to leave the motorcycle fully operable without ever supplying a valid rider PIN. The root flaw is a fail-open ECU design: the peer ECU cannot distinguish an authenticated WCM shutdown pulse from a simple open-circuit condition caused by disconnecting the relevant wire pair, so wire interruption silently suppresses the immobilizer. Reported by ASRG under coordinated disclosure with connector details withheld; no public exploit has been identified and the vulnerability is not confirmed actively exploited (CISA KEV).

RemediationAI

No vendor-released patch has been identified at time of analysis; Polaris Inc. and Indian Motorcycle have not yet published an advisory or firmware fix. ASRG has intentionally withheld specific connector and wire pair details pending vendor remediation, so owners should monitor Indian Motorcycle's official communications and the ASRG disclosure channel for patch availability. As immediate compensating controls, owners should use supplemental physical security measures - disc locks, chain locks secured to immovable objects, or motorcycle covers that conceal body panel access points - to extend the time and visibility required for an attacker to access the WCM harness. GPS tracking devices can support recovery if theft occurs. When a firmware update is released, it should be prioritized: the correct fix is fail-secure ECU logic that treats an open-circuit or disconnected shutdown wire as an immobilization command rather than an operational signal.

Technical ContextAI · show details

The Scout Bobber + Tech employs a Wireless Control Module that communicates anti-theft shutdown commands to a peer Engine Control Unit using a falling-edge voltage transition on a dedicated analog wire pair - a single-ended, voltage-level signaling scheme. CWE-1384 (Improper Handling of Physical Conditions) precisely describes the root cause: the receiving ECU applies fail-open logic, treating the absence of a valid signal identically to an authorized run state. A secure design would require the ECU to default to immobilization (fail-secure) whenever the shutdown wire is in an indeterminate or open-circuit state. The CPE cpe:2.3:a:indian_motorcycle_(polaris_inc.):scout_bobber_+_tech:*:*:*:*:*:*:*:* uses a wildcard version field, indicating no unaffected firmware revision has been identified. This is an embedded automotive firmware issue under Polaris Inc.'s product line.

DescriptionCVE.org

Improper handling of physical conditions in the bike-shutdown control of the Indian Motorcycle Scout Bobber + Tech 2025 model year allows a physical attacker with access to the Wireless Control Module (WCM) wiring harness to bypass the anti-theft shutdown. The WCM signals shutdown to a peer ECU via a falling-edge voltage transition on a dedicated wire pair. The receiving ECU does not distinguish between an active shutdown pulse and an open-circuit / disconnected condition; interrupting the relevant wires leaves the motorcycle fully operable even though the WCM never validated the rider's PIN. Specific connector details have been withheld pending vendor remediation.
