CVE-2026-78169: UTT HiPER 1250GW HTTP Request aspRemoteApConfTempSend strcpy stack-based overflow

A vulnerability was detected in UTT HiPER 1250GW up to 3.2.7-210907-180535. This impacts the function strcpy of the file /goform/aspRemoteApConfTempSend of the component HTTP Request Handler. Performing a manipulation of the argument Profile results in stack-based buffer overflow. The attack is possible to be carried out remotely. The exploit is now public and may be used.

Security readout for executives and security teams

Plain-English summary

A remotely reachable flaw in the UTT HiPER 1250GW management interface can corrupt memory when an authenticated user submits an oversized Profile value. Successful exploitation could compromise confidentiality, integrity, and availability beyond the vulnerable component. Public exploit material exists, but the supplied sources do not establish active exploitation.

Executive priority

Treat as an urgent management-plane risk. Identify affected routers immediately, isolate their administrative interfaces, and seek vendor remediation. Prioritize internet-reachable or broadly accessible devices first. Public exploit availability and potential full-impact compromise justify rapid action, although active exploitation has not been confirmed.

Technical view

The /goform/aspRemoteApConfTempSend HTTP handler reportedly passes the Profile argument to strcpy without adequate bounds checking, causing a stack-based buffer overflow. CVSS 3.1 scores it 9.9: network-accessible, low complexity, low privileges, no user interaction, changed scope, and high impact across confidentiality, integrity, and availability.

Likely exposure

Exposure is most likely where a UTT HiPER 1250GW running firmware up to 3.2.7-210907-180535 has its HTTP management interface reachable by untrusted or low-privileged authenticated users. The bundle does not establish how commonly the product is deployed or whether management access is normally internet-exposed.

Exploitation context

A public exploit reference is listed, increasing near-term misuse risk. Exploitation reportedly requires low privileges and remote access to the HTTP handler. CVE-2026-78169 is not identified as being in CISA KEV by the supplied bundle, and no cited evidence confirms active exploitation in the wild.

Researcher notes

The report maps to CWE-119 and CWE-121 and specifically identifies unsafe strcpy use with the Profile parameter. The CVSS scope change and high impact claims are source assertions. The supplied evidence does not name a patched release, vendor advisory, observed indicators, reliable exploit success conditions, or confirmed exploitation telemetry.

Mitigation direction

  • Check UTT guidance for corrected firmware or vendor-approved remediation; no fixed version is named in the supplied sources.
  • Restrict the management interface to trusted administrative networks and authenticated administrators only.
  • Remove direct internet exposure using firewall rules, VPN access, or equivalent management-plane controls.
  • Monitor the affected endpoint for unusual Profile submissions and unexpected device restarts.

Validation and detection

  • Inventory UTT HiPER 1250GW devices and record their exact firmware versions.
  • Confirm whether /goform/aspRemoteApConfTempSend is reachable from internet, user, wireless, or guest networks.
  • Review account permissions and identify low-privileged users able to access the management interface.
  • Inspect HTTP, authentication, and system logs for suspicious endpoint requests, crashes, or unexplained configuration changes.
  • Verify remediation against current UTT guidance when vendor information becomes available.
