Privilege escalation and file deletion
Published Jun 16, 2020 · Updated Aug 4, 2024
Improper privilege management in Schneider Electric Easergy T300 firmware 1.5.2 and earlier allows remote authenticated users to delete files. The vendor identifies an improper write operation but has not disclosed the affected interface, file-handling locus, or privilege-check failure. Exploitation requires network access and high-privileged authentication, and it grants elevated privileges that can be used to remove files.
