[Bug 1410839] Re: Shell Command injection in ufw_backend.py
I was able to use "iface" to insert a shell command, too.
1.) save a profile wich uses some interface , for example "eth0" to your home directory.
2.) edit the file like this
iface = eth0;xterm;
3.) rename the profile to some other name than before
4.) import the new profile with Gufw from your home directory
5.) use the new profile
6.) xterm starts .... boom :-)

Title:
Shell Command injection in ufw_backend.py
Status in Gufw:
Fix Released
Status in gui-ufw package in Ubuntu:
Confirmed
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.
