Bollocks.
If you have the permissions to place such a DLL you could just as well directly replace filezilla.exe with a malicious executable.
Furthermore, if you had actually checked how and by which other component this library is being loaded, you would have realized that this is an issue you must report to Microsoft, as only they can change Windows itself.

dll library is being execute by FileZilla as this dll library is programmed to be execute in the same folder by FileZilla its not being loaded by any other party but except FileZilla itself.

DLL Hijacking vulnerability exists at this version, FileZilla loads this dll without checking whether it's legitimate to support or it's malicious.

Please do yourself a favor and look at the callstack in debugger at the point this DLL is being loaded.
