CVE-2026-19341

UTT · HiPER 1200GW

A stack-based buffer overflow vulnerability in UTT HiPER 1200GW allows authenticated attackers to potentially execute arbitrary code through memory corruption.

Executive summary

A memory corruption vulnerability in UTT HiPER 1200GW poses a significant risk of arbitrary code execution for authenticated users.

Vulnerability

This vulnerability is a stack-based buffer overflow (CWE-121) caused by improper memory management. The vulnerability requires the attacker to have low-level authenticated access to the device to trigger the memory corruption.

Business impact

The exploitation of this vulnerability could lead to a complete compromise of the affected networking hardware. Given the CVSS score of 8.8, this is a high-severity issue that could result in unauthorized administrative access, network traffic interception, or service disruption, severely impacting organizational network integrity.

Remediation

Immediate Action: Contact UTT support or monitor official vendor channels for the release of a firmware patch addressing this memory corruption flaw.

Proactive Monitoring: Inspect system logs for anomalous crashes or unexpected reboots of the HiPER 1200GW device, which may indicate exploitation attempts.

Compensating Controls: Restrict access to the device management interface to trusted administrative IP addresses only to reduce the attack surface.

Exploitation status

Public Exploit Available: Unknown.

Analyst recommendation

Due to the high CVSS score and the nature of buffer overflow vulnerabilities, this issue presents a critical risk to network infrastructure. Administrators should prioritize securing the management interface and remain vigilant for vendor release announcements regarding a definitive firmware patch.
