CVE-2026-1162 is a buffer overflow vulnerability identified in the UTT HiPER 810 device, version 1.7.4-141218. The vulnerability resides in the strcpy function used in the /goform/setSysAdm endpoint, where improper handling of the passwd1 parameter allows an attacker to overflow the buffer. This flaw can be exploited remotely without any authentication or user interaction, making it highly accessible to attackers. The buffer overflow can lead to arbitrary code execution, potentially allowing attackers to take full control of the affected device. The vulnerability has been assigned a CVSS 4.0 score of 9.3, reflecting its critical nature with high impact on confidentiality, integrity, and availability. Although no active exploitation has been reported in the wild, a public exploit is available, increasing the likelihood of attacks. The vulnerability affects a specific version of the UTT HiPER 810, a device commonly used in telecommunications and network infrastructure. The flaw's exploitation could disrupt network operations, leak sensitive information, or allow attackers to pivot into internal networks. The lack of authentication requirements and the remote attack vector make this vulnerability particularly dangerous. Due to the criticality of the affected device in network environments, exploitation could have widespread consequences.

For European organizations, the impact of CVE-2026-1162 could be severe. The UTT HiPER 810 is often deployed in telecommunications and network infrastructure, which are critical sectors in Europe. Successful exploitation could lead to complete device compromise, enabling attackers to intercept or manipulate network traffic, disrupt services, or use the device as a foothold for further attacks within corporate or governmental networks. This could result in data breaches, service outages, and loss of trust. Critical infrastructure operators, ISPs, and enterprises relying on these devices are at heightened risk. The remote, unauthenticated nature of the exploit increases the attack surface, making it easier for threat actors to target organizations without needing insider access. Given the geopolitical tensions and the importance of secure communications in Europe, this vulnerability could be leveraged for espionage or sabotage. The potential for widespread disruption in telecommunications could affect multiple sectors including finance, healthcare, and public administration.

1. Immediate action should be taken to identify all UTT HiPER 810 devices running version 1.7.4-141218 within the network. 2. Apply vendor patches or firmware updates as soon as they become available; if no patch is currently available, contact UTT support for guidance or mitigations. 3. Restrict network access to the management interface (/goform/setSysAdm) by implementing strict firewall rules and network segmentation, limiting access to trusted administrators only. 4. Employ intrusion detection and prevention systems (IDS/IPS) to monitor for exploit attempts targeting this vulnerability. 5. Disable or restrict remote management features if not required. 6. Conduct regular security audits and vulnerability scans to detect unpatched devices. 7. Implement strong authentication and multi-factor authentication on management interfaces where possible to reduce risk. 8. Monitor public threat intelligence feeds for updates on exploit activity and adjust defenses accordingly. 9. Educate network administrators about the vulnerability and signs of compromise. 10. Consider deploying network anomaly detection tools to identify unusual traffic patterns indicative of exploitation attempts.
