🇰🇷 한글 설명
Iocharger AC 모델의 특정 펌웨어 버전에서 발생하는 커맨드 인젝션 취약점입니다. 공격자가 특정 파라미터를 통해 루트 권한으로 원격 코드 실행(RCE)을 수행할 수 있습니다.
💡 쉬운 설명
전기차 충전기의 소프트웨어 결함을 이용해 해커가 충전기의 모든 제어권을 탈취할 수 있는 위험한 보안 문제입니다. 해커가 충전기를 마음대로 조작하거나 연결된 네트워크로 공격을 확대할 수 있습니다.
🇺🇸 원문 (English)
Command injection in the <redacted> parameter of a <redacted>.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 <redacted> fields. 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 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).
