CVE-2020-7513Network attack vector

Configuration disclosure via cleartext network traffic

Published Jun 16, 2020 · Updated Aug 4, 2024

Cleartext storage in Schneider Electric Easergy T300 firmware 1.5.2 and earlier allows remote attackers to read configuration data. Schneider Electric has not identified the responsible file, service, or protocol beyond stating that configuration traffic exposes cleartext data. Access to the device network and interaction with configuration traffic are required; the bounded consequence is configuration disclosure.
