CVE-2026-75094: COMFAST CF-N1-S CGI mbox-config sub_44B438 os command injection

A flaw has been found in COMFAST CF-N1-S 2.6.0.1. This impacts the function sub_44B438 of the file /cgi-bin/mbox-config?method=SET&section=ptest_ssid of the component CGI Interface. This manipulation of the argument ssid causes os command injection. Remote exploitation of the attack is possible. The exploit has been published and may be used.

Security readout for executives and security teams

Plain-English summary

An authenticated attacker could make an affected COMFAST CF-N1-S execute operating-system commands by supplying a malicious Wi-Fi SSID value. Successful exploitation could compromise the device, disrupt service, and affect connected systems. The issue is remotely reachable and rated critical, but the supplied sources do not establish active exploitation.

Executive priority

Treat confirmed version 2.6.0.1 deployments as urgent, especially when management access crosses untrusted networks. Immediately reduce interface exposure and privileged access, then obtain vendor remediation guidance. Consider isolation or replacement if no supported fix is available. Public exploit material raises urgency, although active exploitation has not been demonstrated by the supplied sources.

Technical view

CVE-2026-75094 affects COMFAST CF-N1-S version 2.6.0.1. The CGI handler sub_44B438 improperly processes the ssid argument at /cgi-bin/mbox-config?method=SET&section=ptest_ssid, enabling OS command injection. CVSS 4.0 scores it 9.4 with network access, low complexity, high privileges, no user interaction, and high impact across confidentiality, integrity, and availability.

Likely exposure

Exposure is limited to COMFAST CF-N1-S devices running version 2.6.0.1 where the affected CGI interface is reachable. The CVSS vector indicates exploitation requires high privileges. Internet-accessible or broadly reachable management interfaces increase practical risk; the supplied evidence does not identify other affected versions or products.

Exploitation context

A public exploit repository is referenced, and the CVSS vector marks proof-of-concept maturity as published. Remote exploitation is reportedly possible, but high privileges are required. This CVE is not listed as KEV in the supplied bundle, and no cited evidence confirms exploitation in operational attacks.

Researcher notes

Evidence identifies a specific CGI route, function, and ssid parameter, mapped to CWE-77 and CWE-78. Published exploit material supports practical concern, but this assessment does not validate its reliability. The bundle provides no vendor advisory, fixed version, detection signatures, or confirmed incident evidence, so affected-version scope and remediation remain incomplete.

Mitigation direction

  • Check COMFAST guidance for fixed firmware or vendor-approved remediation.
  • Restrict the device management interface to trusted administrative networks.
  • Block external access to the affected CGI interface where operationally feasible.
  • Review and minimize accounts holding high administrative privileges.
  • Isolate affected devices until remediation or replacement is available.

Validation and detection

  • Inventory CF-N1-S devices and confirm their installed firmware versions.
  • Verify whether the CGI management interface is reachable from untrusted networks.
  • Review device logs for unexpected configuration changes or command-execution indicators.
  • Confirm administrative accounts are necessary, protected, and limited to trusted operators.
  • After remediation, confirm the affected interface remains restricted and firmware is vendor-approved.
