This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of ChargePoint Home Flex charging stations. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the onboardee module. The issue results from improper access control. An attacker can leverage this vulnerability to execute code in the context of root.

Weakness 

The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.

Extended Description 

Access control involves the use of several protection mechanisms such as:

When any mechanism is not applied or otherwise fails, attackers can compromise the security of the product by gaining privileges, reading sensitive information, executing commands, evading detection, etc. There are two distinct behaviors that can introduce access control weaknesses:

Potential Mitigations 

  • Compartmentalize the system to have “safe” areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
  • Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
