CVE-2017-14422: D-Link Dir-850l Firmware

High severity, CVSS 7.5. EPSS: 1.3% chance of exploitation in the next 30 days.

D-Link DIR-850L REV. A (with firmware through FW114WWb07_h2ab_beta1) and REV. B (with firmware through FW208WWb02) devices use the same hardcoded /etc/stunnel.key private key across different customers' installations, which allows remote attackers to defeat the HTTPS cryptographic protection mechanisms by leveraging knowledge of this key from another installation.

Affected products

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