ABB Terra AC Buffer Overflow Vulnerability (CVE-2025-5517)
The SaiFlow research team has uncovered a buffer overflow vulnerability in ABB Terra AC chargers, that compromises system integrity. We have demonstrated how we can trigger Denial-of-Service (DoS), making the charger inoperative and unresponsive. The vulnerability could potentially be exploited to achieve RCE. Exploitation of the vulnerability requires MITM capabilities with unencrypted communication, or a compromised Charging Station Management System (CSMS).
