CVE-2026-11516
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 vulnerability was found in UTT HiPER 2610G up to 3.0.0-171107. This affects the function strcpy of the file /goform/formNatStaticMap. Performing a manipulation of the argument NatBinds results in buffer overflow. The exploit has been made public and could be used.
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 · moderate confidenceBuffer overflow vulnerability in UTT HiPER 2610G routers (firmware up to 3.0.0-171107) in the /goform/formNATStaticMap handler. The unsafe strcpy function is used to copy the NatBinds argument into a fixed-size buffer without bounds checking, allowing controlled overflow via the HTTP form parameter.

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 router modelAccess the router's web management interface or check the device label/boot logs to confirm the model is UTT HiPER 2610GAffected if The device is not a UTT HiPER 2610G router, then this specific CVE does not apply
-
Determine the firmware versionLog into the router web interface and navigate to System Status or Firmware Upgrade page to read the installed firmware version. Alternatively, check via CLI if telnet/ssh access is availableAffected if The installed firmware version is 3.0.0-171107 or any earlier version, meaning it is within the affected range up to and including that version
-
Verify if the web management interface is accessibleAttempt to reach the router's HTTP/HTTPS management port from the network. Check if port 80 or 443 (or custom port) responds with the router login pageAffected if The router web interface is exposed to untrusted networks, increasing the likelihood of attack
-
Confirm the vulnerable NAT Static Map feature existsAfter logging into the web interface, look for a NAT or Port Forwarding configuration section and check if a Static Map or NAT Static mapping feature is present and configurableAffected if The router firmware contains the /goform/formNATStaticMap function, which is present in affected versions and allows the NatBinds parameter to be manipulated
A user is affected if they are running a UTT HiPER 2610G router with firmware version 3.0.0-171107 or earlier, with the web management interface accessible and the NAT Static Map feature present.

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 when available; until then, restrict network access to the router's web management interface to trusted sources only to reduce attack surface.
