[Bug 1410839] Re: Shell Command injection in ufw_backend.py
Please, if you can, try the final patch (it's the both patchs in this
bug, together).
You will need to restart ufw_frontend.py to the default code, the easy way is:
sudo apt-get purge gufw && sudo apt-get install gufw
Then, apply the patch to ufw_frontend.py.
Thanks in advance!

Title:
Shell Command injection in ufw_backend.py
Status in Gufw:
Fix Committed
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.
