I managed to start xterm (2x) with root rights when the firewall admin exports the profile to a path like
/.../.../;xterm;/.../ so the profile name is not the key but the path in the "file" variable(s) in the export function . For a workaround the export path should not be user editable but a fixed standard path an filename. -- You received this bug notification because you are a member of Gufw Developers, which is subscribed to Gufw. https://bugs.launchpad.net/bugs/1410839 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.
