CVE-2026-2537 Details
Description
A vulnerability was identified in Comfast CF-E4 2.6.0.1. This impacts an unknown function of the file /cgi-bin/mbox-config?method=SET§ion=ntp_timezone of the component HTTP POST Request Handler. Such manipulation of the argument timestr leads to command injection. The attack may be launched remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.
A command injection vulnerability exists in the Comfast CF-E4 WiFi router, specifically in the web management interface of version 2.6.0.1. The issue arises within the '/cgi-bin/mbox-config' endpoint when handling POST requests for the 'ntp_timezone' section. The vulnerability allows authenticated attackers to execute arbitrary commands with root privileges by injecting malicious characters into the 'timestr' parameter. This exploitation is possible because the device fails to properly validate user input, allowing crafted data to be executed as a system command.
