Re: [Bug 1410839] [NEW] Shell Command injection in ufw_backend.py
Hi! Thanks a lot for your feedback!
The user only can to create profiles with letters, numbers, dashes and
underscores.
http://bazaar.launchpad.net/~costales/gui-ufw/gufw-15.04/view/head:/gufw/view/preferences.py#L101
<http://bazaar.launchpad.net/%7Ecostales/gui-ufw/gufw-15.04/view/head:/gufw/view/preferences.py#L101>
A profile with semicolons will be reject.
I was thinking about to filter in the ufw_backend.py in any way?
Best regards!

Title:
Shell Command injection in ufw_backend.py
Status in Gufw:
New
Bug description:
Firewall Administrators can be tricked by someone to export a profile
with Gufw to an special crafted file or path name wich contains shell
code.
reason is this line in ufw_backend.py :
def export_profile(self, profile, file):
commands.getstatusoutput('cp /etc/gufw/' + profile + '.profile ' + file + ' ; chmod 777 ' + file)
The rename and delete funktions are also unsave if profile name
contains shell code, like semicolons.
