CVE-2022-21167
All versions of package masuit.tools.core are vulnerable to Arbitrary Code Execution via the ReceiveVarData<T> function in the SocketClient.cs component.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.40%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
All versions of package masuit.tools.core are vulnerable to Arbitrary Code Execution via the ReceiveVarData<T> 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.
