CVE-2023-43776Public exploit

Device password recovery via weak PRG encoding

Published Oct 17, 2023 · Updated Sep 13, 2024

Weak password encoding in Eaton easyE4 before 2.02 allows physically proximate attackers to recover device password candidates from PRG files. The exported microSD program file contains an encoded password that the published recovery tool rapidly converts into valid cleartext candidates. Access to the exported file and user interaction are required; recovered candidates can unlock protected device areas such as Ethernet access.
