CVE-2026-24444
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 · uneditedSDMC NE6037 cable modem routers running firmware 7.1.6.0.25 and 7.1.6.1.9_B9 contain a hardcoded password vulnerability in the web management interface recovery endpoints (mgmt.php, npcmd.php) that allows unauthenticated attackers to gain root access by submitting the hardcoded credential to the recovery endpoint via HTTP. Attackers can leverage this hardcoded password to enable filtered SSH and Telnet services on the device, resulting in unauthenticated root-level remote access to the underlying system.
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.

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 the device modelAccess the router's web interface or check the device label/menu to confirm the model is SDMC NE6037Affected if The device is an SDMC NE6037 cable modem router
-
Check the installed firmware versionLog into the router web interface and navigate to the status or system information page to view the firmware version, or use the command line and run 'show version' or check /proc/version if accessibleAffected if The firmware version is 7.1.6.0.25 or 7.1.6.1.9_B9
-
Determine if the web management interface is exposed externallyReview router firewall settings and port forwarding rules to check if the web interface (HTTP/HTTPS on ports 80/443) is accessible from external networks rather than only from the local LANAffected if The web management interface (mgmt.php, npcmd.php endpoints) is reachable from untrusted networks
-
Verify SSH or Telnet service statusCheck router settings for SSH or Telnet service enablement, or attempt to connect to the router's IP on ports 22 (SSH) or 23 (Telnet) from the networkAffected if SSH or Telnet services are enabled and accessible on the device
-
Confirm recovery endpoints are accessibleAttempt to access the specific endpoints mgmt.php and npcmd.php via HTTP (for example, http://routerIP/mgmt.php) from an authorized position to verify they respondAffected if The recovery endpoints mgmt.php and npcmd.php are reachable and respond to requests
A user is affected if they have an SDMC NE6037 router running firmware version 7.1.6.0.25 or 7.1.6.1.9_B9 with the web management interface externally accessible, as this allows unauthenticated attackers to use the hardcoded credential on recovery endpoints for root 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 updates when available; meanwhile, block external access to the device's web management interface, SSH, and Telnet ports using network firewalls or disable remote management features entirely.
