CVE-2026-18897
UTT · HiPER 1250GW
A stack-based buffer overflow vulnerability in the UTT HiPER 1250GW router allows for potential memory corruption and system compromise.
Executive summary
A high-severity stack-based buffer overflow in UTT HiPER 1250GW firmware poses a significant risk of remote code execution.
Vulnerability
This vulnerability involves a stack-based buffer overflow and memory corruption flaw. It requires an attacker to have low-level privileges to successfully trigger the vulnerability, as indicated by the PR:L vector.
Business impact
Successful exploitation of this flaw could allow an attacker to execute arbitrary code with elevated privileges on the network appliance. Given the CVSS score of 8.8, this represents a severe risk to network integrity and could lead to total system compromise, unauthorized traffic interception, or the routing of internal traffic to malicious destinations.
Remediation
Immediate Action: Administrators should monitor official UTT support channels for firmware updates and apply them as soon as they become available.
Proactive Monitoring: Review device access logs for unusual patterns or signs of repeated failed login attempts that might precede an exploitation attempt.
Compensating Controls: Restrict management access to the device to a dedicated, isolated administrative network segment to limit the attack surface.
Exploitation status
Public Exploit Available: Unknown.
Analyst recommendation
The vulnerability is rated as high severity due to the potential for full system compromise. Organizations utilizing the UTT HiPER 1250GW should prioritize isolating these devices from external access and applying vendor-supplied patches immediately upon release to mitigate the risk of remote exploitation.
