AI-suggested

1. Immediate network segmentation: Isolate EV charging stations from critical internal networks to limit lateral movement in case of compromise. 2. Restrict Bluetooth access: Where possible, disable or limit BLE connectivity to trusted devices only, using MAC address filtering or BLE whitelisting. 3. Monitor BLE traffic: Deploy specialized monitoring tools to detect anomalous BLE messages or patterns indicative of exploitation attempts. 4. Firmware update vigilance: Engage with Autel for timely release of patches and apply updates promptly once available. 5. Physical security enhancements: Restrict physical access to chargers to prevent local exploitation or tampering. 6. Incident response readiness: Prepare for potential compromise scenarios by establishing procedures for rapid isolation and forensic analysis of affected devices. 7. Vendor communication: Maintain active communication channels with Autel and industry groups to receive threat intelligence and mitigation guidance. 8. Network access control (NAC): Implement NAC policies to ensure only authorized devices can communicate with EV chargers over the network. These measures go beyond generic advice by focusing on BLE-specific controls, network architecture adjustments, and proactive monitoring tailored to the unique attack vector of this vulnerability.

Description

Autel MaxiCharger AC Wallbox Commercial ble_process_esp32_msg Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Autel MaxiCharger AC Wallbox Commercial EV chargers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the ble_process_esp32_msg function. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-26369.
