CVE-2026-75364: n/a
Description
A command injection vulnerability exists in Comfast CF-N1-S firmware 2.6.0.1 and CF-WR630AX (2024-01-30 build) in the update_interface_png SET handler of /usr/bin/webmgnt. The display_name parameter is not sanitized and is used unsafely in a shell command executed with root privileges. This allows a remote authenticated attacker to inject arbitrary commands. The vulnerability has a CVSS score of 6.8, indicating medium severity.

Technical Analysis
The update_interface_png SET handler in /usr/bin/webmgnt on Comfast CF-N1-S firmware 2.6.0.1 and CF-WR630AX (2024-01-30 build) fails to sanitize the user-controlled display_name parameter. This parameter is concatenated via sprintf() into an unquoted shell command `/etc/rrd/graphinterface %s %s` and executed by system() with root privileges. This improper input validation leads to a command injection vulnerability (CWE-78) exploitable by a remote authenticated attacker to execute arbitrary commands with root privileges.
Potential Impact
Successful exploitation allows a remote authenticated attacker to execute arbitrary commands with root privileges on the affected device. This can lead to full system compromise, including confidentiality, integrity, and availability impacts.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary mitigation has been documented. Until a patch is available, restrict access to the affected management interface to trusted users only and monitor for suspicious activity.
