MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1059.004 Unix Shell Execution
Adversaries may abuse Unix shell commands and scripts for execution.
T1202 Indirect Command Execution Stealth
Adversaries may abuse utilities that allow for command execution to bypass security restrictions that limit the use of command-line interpreters.
Why these techniques?

Command injection in webmgnt ntp_timezone function via timestr parameter enables remote exploitation of public-facing web application (T1190), indirect command execution (T1202), and Unix shell command execution (T1059.004).

NVD Description

A 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…

Deeper analysisAI

CVE-2025-9582 is a command injection vulnerability in the Comfast CF-N1 firmware version 2.6.0. The flaw resides in the ntp_timezone function within the /usr/bin/webmgnt file, where manipulation of the timestr argument enables arbitrary command execution. It is associated with CWE-74 (Improper Neutralization of Special Elements) and CWE-77 (Command Injection), carrying a CVSS v3.1 base score of 6.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L).

The vulnerability can be exploited remotely by attackers with low privileges, such as authenticated users, requiring low complexity and no user interaction. Successful exploitation allows limited impacts on confidentiality, integrity, and availability through injected commands, potentially enabling further compromise depending on the attacker's access level.
