Summary

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.

Risk Assessment

An authenticated attacker can execute arbitrary commands with root privileges, leading to full device compromise, including network control or firmware modification.

Recommendation

Update firmware to a patched version and sanitize the display_name parameter before using it in shell commands.
