Physical privilege escalation via credential guessing
Published Jul 13, 2022 · Updated Sep 17, 2024
Improper privilege management in Schneider Electric Acti9 PowerTag Link C allows physically proximate attackers to gain elevated functionality. The authentication mechanism permits elevation through credential guessing; Schneider Electric has not disclosed the specific validation error or code locus. Physical access to an A9XELC10-A device running 1.7.5 and earlier or A9XELC10-B running 2.12.0 and earlier is required; the exposed elevated operations are undisclosed.
