CVE-2026-1162 is a critical security vulnerability identified in the UTT HiPER 810 device, version 1.7.4-141218. The vulnerability arises from improper handling of input in the strcpy function located in the /goform/setSysAdm endpoint. Specifically, the passwd1 parameter is not properly bounded, allowing an attacker to cause a buffer overflow by sending an overly long input string. This buffer overflow can be exploited remotely without requiring authentication or user interaction, making it highly accessible to attackers. The impact of this flaw is severe, as it can lead to arbitrary code execution, full system compromise, or denial of service. The CVSS 4.0 score of 9.3 reflects the critical nature of this vulnerability, with high impact on confidentiality, integrity, and availability, and an exploitability rating indicating low complexity and no privileges or user interaction needed. Although no confirmed active exploitation has been reported, a public exploit is available, increasing the likelihood of attacks. The vulnerability affects a specific version of the UTT HiPER 810, a device likely used in network infrastructure or industrial environments. The lack of official patches at the time of reporting necessitates immediate mitigation efforts to reduce risk.

For European organizations, the impact of CVE-2026-1162 can be substantial, especially for those relying on UTT HiPER 810 devices within their network infrastructure or operational technology environments. Successful exploitation can lead to unauthorized remote code execution, allowing attackers to gain full control over affected devices. This can result in data breaches, disruption of critical services, or pivoting to other internal systems. The compromise of such devices could affect confidentiality by exposing sensitive data, integrity by altering configurations or data, and availability by causing device crashes or denial of service. Given the remote, unauthenticated nature of the exploit, attackers can launch attacks at scale, increasing the risk to large networks. European sectors such as telecommunications, manufacturing, energy, and government infrastructure that deploy these devices are particularly vulnerable. The presence of a public exploit increases the urgency for organizations to act swiftly to prevent potential widespread exploitation.

1. Immediate network segmentation: Isolate UTT HiPER 810 devices from general network access, restricting management interfaces to trusted administrative networks only. 2. Implement strict access control lists (ACLs) and firewall rules to block unauthorized access to the /goform/setSysAdm endpoint. 3. Monitor network traffic for unusual or malformed requests targeting passwd1 parameters or the /goform/setSysAdm path to detect potential exploitation attempts. 4. Apply any available vendor patches or firmware updates as soon as they are released. If no patch is available, consider temporary device replacement or disabling vulnerable services if feasible. 5. Employ intrusion detection/prevention systems (IDS/IPS) with signatures or heuristics targeting this specific exploit. 6. Conduct regular vulnerability scans and penetration tests focusing on UTT HiPER 810 devices to identify exposure. 7. Educate network administrators about this vulnerability and enforce strong password policies and multi-factor authentication where possible to reduce attack surface.
