Subject: Restricting shells...
Date: Tue, 24 Feb 2004 10:42:50 -0700 [thread overview]
Message-ID: <003701c3fafd$9ff50250$6f00000a@jenswin2k> (raw)
This is kinda tricky:
Situation:
- A webserver, hosting a page which has CGIs enabled
- Not-too-bright webdesigner putting up scripts that allow "escaping", by
i.e. sending a receipient of someone@somewhere;/bin/bash -i
I want to restrict _interactive_ bash shells (other shells are not a concern
yet). Is there _any_ way to do that, short of wrapping bash into a little
program that checks by whom bash got called and with which parameters?
Thanks
Jens
