CVE-2026-75364Public exploit

Root command execution via unquoted display_name

Published Aug 26, 2026 · Updated Aug 26, 2026

OS command injection in Comfast CF-N1-S 2.6.0.1 and CF-WR630AX 2024-01-30 firmware allows remote authenticated users to execute commands. The update_interface_png SET handler in /usr/bin/webmgnt inserts display_name with sprintf() into an unquoted /etc/rrd/graphinterface command string passed to system(). Access to the authenticated management interface from an adjacent network is required; injected commands run as root and can fully control the device.
