Technical details
The firmware update process for the basemodule of CHARX SEC-3xxx charging controllers (models 3000, 3050, 3100, and 3150) only validates the CRC32 checksum of update packages. It lacks cryptographic signature verification (CWE-347), which is necessary to ensure the authenticity and integrity of the firmware. An unauthenticated remote attacker can exploit this by delivering a modified or malicious firmware image to the device. Successful exploitation results in full system compromise, including loss of confidentiality, integrity, and availability. The vulnerability is addressed in firmware version 1.9.1.
