We use cygwin including installing some services via cygrunsrv. We have 
had some users run vulnerability scans which flag the installed services 
due to an unquoted service path (CWE-428 [1]). I haven't been able to 
find any discussion of this in the archives except for the "cygrunsrv -L 
outputs nothing if service paths are quoted" [2]. In that message, 
another user manually added quotes to resolve the vulnerability scan but 
then 'cygrunsrv -L' no longer listed installed services. That issue was 
fixed.

I did come up with a simple patch (attached) that worked for my limited 
use case. But there may be considerations for global usage of which I am 
unaware.

Should cygrunsrv be updated to automatically include the quotes?

Thanks,
James
