Technical details

The vulnerability is an OS command injection in interface_wireless_clone() that fails to escape user-supplied wireless parent interface names before passing them to ifconfig shell commands. Authenticated users with Wireless Edit or Interface Assignments privileges can inject commands via interfaces_wireless_edit.php or interfaces_assign.php by supplying values like "ath0;<cmd>". The attacker gains root command execution on the firewall appliance.
