CVE-2024-43652
Published: 09 January 2025
Description
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 <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.
Security Summary
CVE-2024-43652 is an improper neutralization of special elements used in a command (CWE-78, CWE-250), enabling OS command injection with root privileges. The vulnerability affects Iocharger firmware for AC model chargers in versions prior to 24120701.
Exploitation requires a low-privilege account to access the affected binary or tricking a user with such access into executing a crafted HTTP request. Successful attacks grant full root control over the charging station, allowing arbitrary addition, modification, and deletion of files and services. The CVSS v3.1 base score is 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), with moderate likelihood due to the binary not being directly exposed via the web interface, though it closely resembles the binary in the Iocharger Pedestal charging station.
