Summaryinfo

A vulnerability identified as critical has been detected in Iocharger. This impacts an unknown function. The manipulation leads to os command injection. This vulnerability is referenced as CVE-2024-43648. Remote exploitation of the attack is possible. No exploit is available. You should upgrade the affected component.

Detailsinfo

A vulnerability was found in Iocharger. It has been rated as critical. This issue affects some unknown functionality. The manipulation with an unknown input leads to a os command injection vulnerability. Using CWE to declare the problem leads to CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Command injection in the parameter of a .exe request leads to remote code execution as the root user. This issue affects Iocharger firmware for AC models before version 24120701. Likelihood: Moderate – This action is not a common place for command injection vulnerabilities to occur. Thus, an attacker will likely only be able to find this vulnerability by reverse-engineering the firmware or trying it on all fields. The attacker will also need a (low privilege) account to gain access to the binary, or convince a user with such access to execute a payload. Impact: Critical – The attacker has full control over the charging station as the root user, and can arbitrarily add, modify and delete files and services. CVSS clarification. The attack can be executed over any network connection the station is listening to and serves the web interface (AV:N), and there are no additional security measure sin place that need to be circumvented (AC:L), the attack does not rely on preconditions (AT:N). The attack does require authentication, but the level of authentication is irrelevant (PR:L), it does not require user interaction (UI:N). If is a full system compromise, potentially fully compromising confidentiality, integrity and availability of the devicer (VC:H/VI:H/VA:H).  A compromised charger can be used to "pivot" onto networks that should otherwise be closed, cause a low confidentiality and interity impact on subsequent systems. (SC:L/SI:L/SA:H). Because this device is an EV charger handing significant amounts of power, we suspect this vulnerability can have a safety impact (S:P). The attack can be automated (AU:Y).

The weakness was published by Wilco Van Beijnum as DIVD-2024-00035. It is possible to read the advisory at csirt.divd.nl. The identification of this vulnerability is CVE-2024-43648 since 08/14/2024. The exploitation is known to be easy. The attack may be initiated remotely. The technical details are unknown and an exploit is not publicly available. The attack technique deployed by this issue is T1202 according to MITRE ATT&CK.

Upgrading to version 24120701 eliminates this vulnerability.
