Subject Re: Potential security issue with default karaf console access control lists?
Date Thu, 31 Aug 2017 12:04:28 GMT
I agree: as we did for vi/edit command, we should limit cat to admin role.

Can you create a Jira about that ?

Thanks !

hence can potentially navigate the visible filesystem.  This doesn't feel very desirable.
