CVE-2022-21167

Description

All versions of package masuit.tools.core are vulnerable to Arbitrary Code Execution via the ReceiveVarData function in the SocketClient.cs component. The socket client in the package can pass in the payload via the user-controllable input after it has been established, because this socket client transmission does not have the appropriate restrictions or type bindings for the BinaryFormatter.
