> The shell:cat command has no access control list associated with it in the default configuration.
> The same is true of the "shell:ls" command. There may be other shell: commands too that can provide filesystem access. I don't know whether cd, pwd for example should be secured. "tac" most certainly should.
> This means that any user that can access the ssh console can navigate the filesystem, reading and writing files as they like.
> For example, given the default configuration, if I have a "normal" user and can therefore access the console, I can use shell commands to find our or guess the location of the karaf install (shell:pwd will do that), then cat the contents of the etc/users.properties file and find out all users passwords (in the default configuration the passwords are in plain text). I can also cat the etc/host.key file which would seem undesirable. 
> tac clearly would be a very dangerous command to have access to. It seems likely that I could subvert many things by just writing directly to configuration files using tac. I could, for example, change, or at least invalidate the admin password by rewriting the users.properties file.
> All in all this feels like a major issue.
