AI-suggested
1. Immediate deployment of vendor patches or firmware updates once available is critical; organizations should maintain close communication with Autel for updates. 2. Network segmentation should be enforced to isolate EV charging stations from broader corporate or public networks, limiting attacker access to the vulnerable devices. 3. Implement strict network access controls and monitoring for anomalous DLB_SlaveRegister message traffic to detect and block exploitation attempts. 4. Use network intrusion detection/prevention systems (IDS/IPS) with custom signatures tailored to detect malformed or oversized DLB_SlaveRegister packets. 5. Restrict physical and logical access to charging stations, especially in public or semi-public environments, to reduce the risk of network-adjacent attackers. 6. Conduct regular security assessments and penetration testing focused on EV charging infrastructure to identify and remediate vulnerabilities proactively. 7. Maintain comprehensive logging and incident response plans specific to EV infrastructure to enable rapid detection and mitigation of exploitation attempts. 8. Consider deploying compensating controls such as application-layer firewalls or protocol whitelisting to validate message integrity before processing.
Description
Autel MaxiCharger AC Wallbox Commercial DLB_SlaveRegister Heap-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 handling of DLB_SlaveRegister messages. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-26327.
