CVE-2024-43651
Published: 09 January 2025
Summary
CVE-2024-43651 is a critical-severity OS Command Injection (CWE-78) vulnerability in Divd (inferred from references). Its CVSS base score is 9.3 (Critical).
Operationally, ranked in the top 12.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
CVE-2024-43651 is a command injection vulnerability (CWE-78) that permits OS command execution as root. It affects Iocharger AC charging station firmware prior to version 241207101 and stems from improper neutralization of special elements in commands processed by an internal binary that is not directly exposed through the web interface.
An attacker with a low-privilege account, or who can induce such a user to submit a crafted HTTP request, can trigger the flaw to obtain full root control. This grants arbitrary file and service modification on the device, enabling potential lateral movement into adjacent networks and creating a safety risk because the charger handles significant electrical power.
Advisories published by DIVD CSIRT at the referenced URLs identify the affected firmware versions and recommend updating to 241207101 or later. The EPSS score rose from lower values to a peak of 0.0697 on 2025-12-11 before receding to the current 0.0341, indicating a temporary increase in exploitation interest after disclosure.

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 connection serving the web interface is vulnerable (AV:N) and there are no additional measures to circumvent (AC:L) nor does the attack require special conditions to be present (AT:N). The attack requires authentication, but the level does not matter (PR:L), nor is user interaction required (UI:N). The attack leads to a full compromised (VC:H/VI:H/VA:H) and a compromised device can be used to potentially "pivot" into a network that should nopt be reachable (SC:L/SI:L/SA:H). Because this is an EV charger handing significant power, there is a potential safety impact (S:P). THe attack can be autometed (AU:Y).

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Platform-independent apps typically execute inside a managed runtime or sandbox that restricts direct OS command execution, reducing the ability to exploit OS command injection.
Policy promotes least privilege by defining necessary privileges and management commitment to them.
Supervision detects and allows removal of unnecessary privileges that enable execution with excess rights.
Reviewing accounts for compliance, disabling/removing unneeded accounts, and aligning with termination processes prevents execution with unnecessary privileges.
Separation of duties prevents any single user from holding all privileges needed to complete a critical task, directly reducing execution with unnecessary privileges.
Directly prevents execution with more privileges than needed for assigned tasks.
Role-based training on least privilege principles reduces the chance personnel assign or retain unnecessary privileges.
Analysis of audit records can identify execution with unnecessary privileges through unusual activity patterns.
