## Beschreibung

Comfast CF-N1-S firmware 2.6.0.1 and CF-WR630AX (2024-01-30 build), the update_interface_png SET handler in /usr/bin/webmgnt fails to sanitize the display_name parameter. User-controlled input is concatenated via sprintf() into the unquoted shell command `/etc/rrd/graphinterface %s %s` and executed by system() with root privileges. A remote authenticated attacker can inject arbitrary commands
