CVE-2026-9632 UTT CVE debrief

A stack-based buffer overflow vulnerability exists in the UTT HiPER 1250GW router firmware through version 3.2.7-210907-180535. The vulnerability resides in the `strcpy` function within the `/goform/formGroupConfig` endpoint of the Web Management Interface. An attacker with low privileges can remotely trigger the overflow by manipulating the `Profile` argument, potentially achieving high impact on confidentiality, integrity, and availability. The CVSS 4.0 score of 7.4 (HIGH) reflects network attack vector, low attack complexity, and no required user interaction. Public exploit availability increases immediate risk.

Who should care

Network administrators managing UTT HiPER 1250GW deployments; security teams responsible for edge network infrastructure; organizations using UTT networking equipment for branch office or SMB routing.

Technical summary

The vulnerability is a classic stack-based buffer overflow (CWE-121) via unsafe `strcpy` usage in the `formGroupConfig` handler. The `Profile` parameter lacks proper bounds checking, allowing remote attackers to overwrite return addresses. Attack complexity is low with no user interaction required. The affected component is the administrative web interface, typically exposed on TCP/80 or TCP/443. Exploitation could yield complete device compromise given the privileged context of the web management process.

Defensive priority

HIGH

Recommended defensive actions

  • Apply vendor firmware update if available; no patched version confirmed in source data
  • Restrict Web Management Interface access to trusted administrative hosts via network segmentation
  • Monitor for anomalous requests to `/goform/formGroupConfig` endpoint containing oversized `Profile` parameters
  • Disable remote Web Management Interface access if not operationally required
  • Review device logs for exploitation indicators pending vendor security advisory

Evidence notes

Vulnerability identified through Vuldb CNA submission. Affected function and endpoint confirmed via source references. Vendor attribution marked low confidence due to 'Unknown Vendor' classification in source data; 'UTT HiPER' product identification derived from CVE description text.
