CVE-2026-9627
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 security flaw has been discovered in UTT HiPER 1200GW up to 2.5.3-170306. This impacts the function strcpy of the file /goform/setSysAdm of the component Web Management Interface. The manipulation of the argument sysAdmUser/sysAdmPass results in buffer overflow. The attack can be launched remotely. The exploit has been released to the public and may be used for attacks.
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 · high confidenceBuffer overflow vulnerability in UTT HiPER 1200GW router web management interface. The unsafe strcpy function in /goform/setSysAdm processes sysAdmUser and sysAdmPass parameters without bounds checking, allowing remote attackers to overflow buffers via crafted input.

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 modelLog into the router's web interface or check the device label to confirm it is a UTT HiPER 1200GW router. Alternatively, check the administrative interface or SNMP for the model identifier.Affected if The device is not a UTT HiPER 1200GW router, then this specific CVE does not apply.
-
Check the firmware versionAccess the router's web management interface and navigate to the System Status or Firmware Version page. Compare the displayed firmware version against 2.5.3-170306. If the version cannot be obtained via the GUI, check the router's backup configuration file or use TFTP/SSH to retrieve the version if accessible.Affected if The installed firmware version is 2.5.3-170306 or any earlier version, then the device is within the affected range.
-
Verify the Web Management Interface is enabledIn the router's administrative interface, locate the settings for the Web Management Interface (often under Administration, Access Control, or Security settings). Confirm that the HTTP or HTTPS web interface is enabled and accessible from the network segment in question.Affected if The Web Management Interface is disabled and not accessible, the attack surface for this vulnerability may be reduced, though the vulnerability still exists in the firmware.
-
Confirm the affected form endpoint existsAttempt to access the URL path /goform/setSysAdm on the router's web interface (e.g., http://router-ip/goform/setSysAdm). The presence of this endpoint indicates the vulnerable form handler is installed.Affected if The /goform/setSysAdm endpoint responds (even with an error), the vulnerable code path is present on the device.
A user is affected if the device is a UTT HiPER 1200GW router running firmware version 2.5.3-170306 or earlier, with the Web Management Interface enabled and the /goform/setSysAdm endpoint accessible.

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; if no patch exists, consider network segmentation to limit exposure to the web management interface or device replacement.
