Upload command not working

[gator-dev]

I tried to upload a small plain text file to a beacon and while the beacon received the task and created a file in the appropriate location, the file was empty. I've tried troubleshooting but am having trouble debugging the beacon end of the connection. I tested this on a Windows 10 64bit version 20H2 system with secure/static, secure/staged, non-secure/static, non-secure staged beacon types as well as with and without beacon debug enabled but all resulted in a empty file. Any pointers on debugging the code on the distant end or help in resolving/confirming this issue would be appreciated.

It seems b64_out (here) is empty for some reason - haven't figure out why, yet.

@gator-dev thank for reporting the bug. @glides would appreciate your help with this.

I think I found a few issues. 1) The ResBuffer needs to be initialized with zeroes in order to prevent the initial asprintf() from appending garbage data. 2) Added a nul byte to terminate the decoded data 3) Close the file descriptor after writing the decoded data to file.
My initial fixes can be viewed here.
I still want to test some more edge cases and maybe add some additional error checking before doing a pull request but would appreciate it if someone could take a look and validate this fixes the issue for them.

I sent you an email earlier. Is it possible you can hop on Discord? The link is on the README.
I'll clone your fork and test now.
