invalid chars allowed in scanner name

[scrissti]

If scanner name contains space character it will fail execution:

I'd say this is kind of expected, considering this is a regular shell command being called in the terminal: python manage.py run_scanner <scanner_name> <extra_args>. Furthermore, if extra_args contain spaces it might break the scanner argument list too.

What we could do to ensure this does not happen is to create a field validator for scanner names and not allow whitespace characters!?

Field validator would make sense indeed.

Also, on mobile right now and can't get the link, but it has been mentioned that dkron async commands could be reworked to not rely on shell parsing (as many issues come out of it).

One quick solution in this case, as dkron allows spaces, could be to properly quote/escape the parameters in the shell
