The issues were identified in an Eltima product called ‘USB Over Ethernet’, which provides remote USB redirection functionality and which is implemented in some cloud products with several modifications.
In Amazon WorkSpaces, SentinelOne’s SentinelLabs explains, the library allows users to redirect USB devices so they can connect them directly from a remote desktop.
Responsible for the redirection are two drivers that are flawed, and which might have been vulnerable since the beginning of 2020, SentinelLabs researchers say.
