Quick assessment

Affected
Indian Motorcycle Scout Bobber + Tech
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Indian Motorcycle Scout Bobber + Tech是日本Indian Motorcycle公司的一款中量级巡航摩托车。 Indian Motorcycle Scout Bobber + Tech 2025版本存在安全漏洞，该漏洞源于攻击者通过强制无线控制模块进入CAN总线关闭状态绕过摩托车的防盗关闭，攻击者使用已知的CAN错误帧注入技术针对周期性WCM传输，驱动WCM CAN控制器的发送错误计数器超过总线关闭阈值，之后WCM停止发送所有消息包括关闭命令，其他ECU不将WCM静默解释

Vulnerability Title
Indian Scout Bobber 2025 WCM CAN bus-off attack silently bypasses anti-theft shutdown
Source: CVE Program / CVE List V5
Vulnerability Description
Expected behavior violation in the in-vehicle network of the Indian Motorcycle Scout Bobber + Tech 2025 model year allows an adjacent-network attacker to bypass the motorcycle's anti-theft shutdown by forcing the Wireless Control Module (WCM) into the CAN bus-off state. Using a well-known CAN error-frame injection technique against a periodic WCM transmission, the attacker drives the WCM CAN controller's transmit error counter past the bus-off threshold, after which the WCM stops transmitting all messages, including the shutdown command. Peer ECUs do not interpret WCM silence as a security event and continue normal operation, allowing the motorcycle to be operated despite the immobilizer never having been unlocked. Specific protocol details have been withheld pending vendor remediation.
