Subject: [FD] - Auth Bypass (Fat Client)


Product: Fat Client
Tested version: 3.3.6 but newer version high likely also affected

This vulnerability was identified and reported promptly to the vendor in
April 2020.
The answer was they do not see any risk here.

Anyway I would like to share my POC video, only for learning purposes.

According to the vendor, there is no risk here, on the other hand, I built
up a playground and being a Domain Admin I could gain normal user's storage access.

Personally I do not recommend using this solution in an environment where
somebody can access your C drive (using Windows Domain or common machines -
library, net coffee, and so on...)


Kind regards,
Balazs Hambalko
