High option is not working for securityLevel in Tftpd settings

[Former user]

We observed the problem that high option is not working in Tftpd64: Settings. Even if we send empty file name still it is failing For High security level, we are providing file name to lookup the stat function. Which expects file path but getting the file name. Instead we can send the full file name in SecAllowSecurity() function.

Modified above mentioned description

In windows OS, We observed the problem that high option is not working, even if there is an empty file in TFTP server.
So we have analyzed the code base, looks like TFTP uses stat function to check the size. Unfortunately the file path is not given along with the file name while stat function is getting called.
This code needs to be corrected. Please find the attached image for reference.
