Description
ChargePoint Home Flex revssh Service Command Injection Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of ChargePoint Home Flex devices. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of OCPP messages. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-26338.

Executive Summary

CVE-2026-4157 is a remote code execution vulnerability in ChargePoint Home Flex devices, specifically in the revssh service.

The vulnerability arises from improper validation of user-supplied strings within the handling of OCPP (Open Charge Point Protocol) messages.

Because of this lack of validation, a network-adjacent attacker can execute arbitrary system commands without needing authentication.

Successful exploitation allows the attacker to run code with root privileges on the affected device.

Impact Analysis

This vulnerability can have severe impacts as it allows an attacker to execute arbitrary code with root privileges on the affected ChargePoint Home Flex device.

Since no authentication is required, an attacker with adjacent network access can compromise the device.

  • Confidentiality impact: attacker can access sensitive information.
  • Integrity impact: attacker can modify system files or configurations.
  • Availability impact: attacker can disrupt or disable device functionality.
Compliance Impact

The vulnerability allows remote code execution with root privileges on ChargePoint Home Flex devices without authentication, impacting confidentiality, integrity, and availability of the system.

Such impacts on confidentiality and integrity could potentially lead to non-compliance with standards and regulations like GDPR and HIPAA, which require protection of sensitive data and system integrity.

However, the provided information does not explicitly state the direct effects on compliance with these standards.
