AI-suggested
- Immediate deployment of vendor-provided patches or firmware updates once available is critical.
- Implement network segmentation to isolate Tesla Wall Connectors from critical IT and OT networks, limiting attacker lateral movement if a device is compromised.
- Employ network-level protections such as firewalls and intrusion detection/prevention systems (IDS/IPS) configured to detect and block anomalous HTTP requests, especially those with suspicious Content-Length headers.
- Restrict network access to Wall Connectors by allowing only trusted management and monitoring systems to communicate with them, minimizing exposure to network-adjacent attackers.
- Conduct regular security assessments and vulnerability scans on connected devices to identify unpatched or vulnerable Wall Connectors.
- Monitor device logs and network traffic for unusual activity indicative of exploitation attempts.
- Engage with Tesla support or authorized service providers for guidance on secure configuration and incident response procedures related to Wall Connectors.
Description
Tesla Wall Connector Content-Length Header Improper Input Validation Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Tesla Wall Connector devices. Authentication is not required to exploit this vulnerability. The specific flaw exists within the parsing of the HTTP Content-Length header. The issue results from the lack of proper validation of user-supplied data, which can result in memory access past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-26300.
