CVE-2025-9582
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA flaw has been found in Comfast CF-N1 2.6.0. Affected is the function ntp_timezone of the file /usr/bin/webmgnt. Executing manipulation of the argument timestr can lead to command injection. The attack may be launched remotely. The exploit has been published and may be used.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe Comfast CF-N1 wireless router firmware 2.6.0 contains a command injection vulnerability in the web management binary (/usr/bin/webmgnt). The ntp_timezone function improperly sanitizes the timestr parameter, allowing an unauthenticated remote attacker to inject arbitrary shell commands by manipulating this argument through the web interface.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify device model and firmware versionAccess the router web interface and navigate to System or Administration settings to find the firmware version, or use the router's administrative CLI if availableAffected if The device is a Comfast CF-N1 router running firmware version 2.6.0 exactly
-
Verify the web management binary existsIf you have shell access to the router, check for the existence of /usr/bin/webmgnt; otherwise, determine if the web management interface is reachable at the device's IP addressAffected if The binary /usr/bin/webmgnt exists on the device and the web interface responds to requests
-
Confirm the ntp_timezone function is accessibleAccess the router's web interface and locate the NTP or timezone settings page, typically found under Advanced or Time settings; observe if a timestr parameter can be submittedAffected if The NTP/timezone configuration page accepts input through a parameter named timestr
-
Check if remote web management is enabledReview the router's administrative settings to determine if remote web management is enabled, and verify firewall rules that control access to ports 80/443 from external networksAffected if The web management interface is accessible from untrusted networks or the internet
A user is affected if they are running Comfast CF-N1 firmware version 2.6.0 and the web management interface with the ntp_timezone function is exposed to network access.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor firmware update if available; otherwise restrict access to the device's management interface using firewall rules or by disabling remote web administration to prevent external exploitation.
