CVE-2024-43654
Published: 09 January 2025
Description
Improper Neutralization of Special Elements used in a Command ('Command Injection') vulnerability in Iocharger firmware for AC models allows OS Command Injection as root This issue affects all Iocharger AC EV charger models on a firmware version before 25010801. Likelihood: Moderate – The <redacted> 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 <redacted> 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).
Security Summary
CVE-2024-43654 is an improper neutralization of special elements used in a command, classified as an OS Command Injection vulnerability (CWE-78, CWE-250), in the firmware of Iocharger AC EV charger models. It affects all such models running firmware versions prior to 25010801, allowing command injection with root privileges.
An attacker with low-privilege account access to the vulnerable binary—or able to convince such a user to execute a crafted HTTP request—can exploit this over any network interface serving the web UI. Exploitation requires no additional security bypasses or user interaction beyond initial low-privilege authentication (AV:N/AC:L/PR:L/UI:N), granting full root control of the charging station for arbitrary addition, modification, or deletion of files and services. This yields critical impact (CVSS 8.8; 3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), including potential network pivoting (SC:L/SI:L/SA:H) and physical safety risks from the charger's high-power handling capabilities (S:P), with automated attack potential (AU:Y).
