CVE-2017-14429
B (with firmware through FW208WWb02) devices allows unauthenticated remote code execution as root because /etc/services/INET/inet_ipv4.php mishandles shell metacharacters, affecting generated files such as WAN-1-udhcpc.sh.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.92%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
