CVE-2020-7510Network attack vector

Unauthenticated private-key disclosure via undisclosed mechanism

Published Jun 16, 2020 · Updated Aug 4, 2024

Information exposure in Schneider Electric Easergy T300 firmware 1.5.2 and earlier allows remote attackers to obtain private keys. The vendor identifies the exposed key material but does not disclose the component, request, or data-handling operation that returns it. Network access without authentication is sufficient, and the documented impact is limited to disclosure of private keys.
