Security Considerations
|
|
~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Running a Telegram Bot means you are conneted to the public, you never
|
|
know whats send to your Bot.
|
|
|
|
Bash scripts in general are not designed to be bullet proof, so consider
|
|
this Bot as a proof of concept. More concret examples of security
|
|
problems is bash's 'quoting hell' and globbing.
|
|
https://unix.stackexchange.com/questions/171346/security-implications-of-forgetting-to-quote-a-variable-in-bash-posix-shells[Implications
|
|
of wrong quoting]
|
|
|
|
Whenever you are processing input from outside your bot you should
|
|
disable globbing (set -f) and carefully quote everthing.
|
|
|
|
To improve you scripts we recommend to lint them with
|
|
https://www.shellcheck.net/[shellcheck]. This can be done online or you
|
|
can https://github.com/koalaman/shellcheck#installing[install shellcheck
|
|
locally]. bashbot itself is also linted by shellcheck.
|
|
|
|
Run your Bot as a restricted user
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Every file your bot can write is in danger to be overwritten/deleted, In
|
|
case of bad handling of user input every file your Bot can read is in
|
|
danger of being disclosed.
|
|
|
|
Never run your Bot as root, this is the most dangerous you can do!
|
|
Usually the user 'nobody' has almost no rigths on Unix/Linux systems.
|
|
See Expert use on how to run your Bot as an other user.
|
|
|
|
Secure your Bot installation
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Everyone who can read your Bot files can extract your Bots data.
|
|
Especially your Bot Token in `token` must be protected against other
|
|
users. No one exept you should have write access to the Bot files. The
|
|
Bot itself need write access to `count` and `tmp-bot-bash` only, all
|
|
other files should be write protected.
|
|
|
|
Runing `./bashbot.sh init` sets the Bot permissions to reasonable
|
|
default values as a starting point.
|
|
|
|
Is this Bot insecure?
|
|
^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
No - its not less (in)secure as any other Bot written in any other
|
|
language. But you should know about the implications ...
|
|
|
|
That's it!
