CVE-2026-9627: UTT HiPER 1200GW Web Management setSysAdm strcpy buffer overflow

A 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.

Analyst readout for executives and security teams

Plain-English summary

CVE-2026-9627 is a critical buffer overflow in the UTT HiPER 1200GW web management interface. A remote authenticated user can trigger memory corruption through administrator username or password fields. The public record says exploit material is available, but the provided sources do not confirm active exploitation.

Executive priority

Treat this as urgent for any exposed or business-critical UTT HiPER 1200GW deployment. Prioritize containment of management access while confirming vendor remediation, because the vulnerability is critical and public exploit material is reported.

Technical view

The flaw affects /goform/setSysAdm in the Web Management Interface and involves unsafe strcpy handling of sysAdmUser and sysAdmPass. VulDB maps it to CWE-119 and CWE-120 with CVSS 2.0 score 9.0, network attack vector, low complexity, and authentication required.

Likely exposure

Exposure is most likely where UTT HiPER 1200GW devices running firmware 2.5.3-170306, or versions described as up to that build, have web management reachable by administrators or untrusted networks.

Exploitation context

The source bundle states a public exploit has been released and may be used. KEV is false, and no cited source in the bundle confirms in-the-wild exploitation. Authentication is required, which limits but does not remove business risk.

Researcher notes

Evidence supports a remote authenticated buffer overflow in the web management password and username update path. The bundle does not provide vendor patch details, exploitation telemetry, or a confirmed affected-version range beyond the reported 2.5.3-170306/up-to wording.

Mitigation direction

  • Check UTT advisories and support channels for fixed firmware or official mitigation guidance.
  • Restrict web management access to trusted admin networks or VPN-only paths.
  • Remove internet exposure for the device management interface.
  • Review and harden administrator account access on affected devices.
  • Monitor for unexpected management changes, crashes, or reboots.

Validation and detection

  • Inventory UTT HiPER 1200GW devices and record firmware versions.
  • Confirm whether any device runs 2.5.3-170306 or versions reported as affected.
  • Check whether /goform/setSysAdm is reachable from untrusted networks.
  • Review access logs for unusual authenticated management activity.
  • Avoid using public exploit material against production devices.
