AI-suggested
Users should monitor the vendor's advisory for updates. Until a fix is released, restrict access to application instances and backend servers to trusted personnel only to reduce the risk of exploitation.
Description
Multiple BinSoft products perform client-side authentication. An attacker with access to any application instance connected to the backend server can bypass the login verification process by manipulating the application binary and authenticate as an arbitrary user. The described issue affects all published versions. The vendor stated that this issue is a direct result of the architecture model in which the software is distributed, and that it will be mitigated with a corrected installation manual.
