CVE-2017-14429: D-Link Dir-850l Firmware

Critical severity, CVSS 9.8. EPSS: 4.9% chance of exploitation in the next 30 days.

The DHCP client on D-Link DIR-850L REV. A (with firmware through FW114WWb07_h2ab_beta1) and REV. 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.

Affected products

• D-Link Dir-850l Firmware: before fw114wwb07_h2ab (fixed in fw114wwb07_h2ab); version fw114wwb07_h2ab only; up to and including fw208wwb02
