CWE ID Description
CWE-121 A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
CWE-119 The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.

Executive Summary

CVE-2026-78169 is a stack-based buffer overflow in the UTT HiPER 1250GW router firmware up to version 3.2.7-210907-180535. It occurs in the HTTP Request Handler's /goform/aspRemoteApConfTempSend endpoint when the Profile argument is manipulated, causing an unsafe strcpy operation to overflow the stack.

Detection Guidance

To detect this vulnerability, monitor network traffic for HTTP POST requests targeting the /goform/aspRemoteApConfTempSend endpoint with unusually long Profile parameter values. Check for buffer overflow attempts by inspecting logs for crashes or malformed requests in UTT HiPER 1250GW devices running firmware up to v3.2.7-210907-180535.

Impact Analysis

This vulnerability allows remote attackers to cause a denial of service or execute arbitrary code on the router. It may lead to unauthorized access to router configuration, potential loss of network connectivity, or enable further attacks against devices on the same network.

Compliance Impact

This vulnerability could lead to unauthorized access to router configurations, potentially exposing sensitive data. For GDPR, this may result in unauthorized data processing or breaches. For HIPAA, it could compromise protected health information if the router is used in healthcare environments. The lack of access controls and remote exploitability increases compliance risks.

Mitigation Strategies

Immediately update the UTT HiPER 1250GW firmware to the latest version beyond v3.2.7-210907-180535. Disable remote access to the /goform/aspRemoteApConfTempSend endpoint if not required. Implement network-level protections to block malformed HTTP requests targeting this endpoint.
