Detailsinfo

A vulnerability was found in Iocharger and classified as critical. This issue affects an unknown code of the component HTTP Handler. 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:

Improper Neutralization of Special Elements used in a Command ('Command Injection') vulnerability  allows OS Command Injection as root This issue affects Iocharger firmware for AC model chargers before version 24120701. Likelihood: Moderate – The binary does not seem to be used by the web interface, so it might be more difficult to find. It seems to be largely the same binary as used by the Iocharger Pedestal charging station, however. 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 crafted HTTP request. 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: Any network interface serving the web ui is vulnerable (AV:N) and there are not additional security measures to circumvent (AC:L), nor does the attack require and existing preconditions (AT:N). The attack is authenticated, but the level of authentication does not matter (PR:L), nor is any user interaction required (UI:N). The attack leads to a full compromised (VC:H/VI:H/VA:H), and compromised devices can be used to pivot into networks that should potentially not be accessible (SC:L/SI:L/SA:H). Becuase this is an EV charger handing significant power, there is a potential safety impact (S:P). This attack can be automated (AU:Y).

The weakness was presented 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-2024-43653 since 08/14/2024.
