CVE-2026-2080 identifies a command injection vulnerability in the UTT HiPER 810 device, version 1.7.4-141218. The flaw exists in the setSysAdm function located in the /goform/formUser endpoint, where the passwd1 parameter is improperly handled, allowing an attacker to inject arbitrary commands. This vulnerability can be exploited remotely without requiring user interaction or prior authentication, which significantly increases the attack surface. The CVSS 4.0 score of 8.6 (high severity) reflects the vulnerability's potential to compromise confidentiality, integrity, and availability of the device. The vulnerability could allow attackers to execute system-level commands, potentially leading to full device compromise, data exfiltration, or disruption of services. Although no patches have been released and the vendor has not responded to the disclosure, public exploit code is available, raising the likelihood of exploitation. The vulnerability affects a specific firmware version, indicating that organizations running this version are at risk. The lack of authentication and user interaction requirements makes this vulnerability particularly dangerous in exposed network environments. The device is often used in telecommunications or network infrastructure contexts, which increases the criticality of this vulnerability. Defenders must prioritize detection and containment until a patch is available.

For European organizations, the impact of CVE-2026-2080 is substantial. The UTT HiPER 810 is typically deployed in telecommunications and network infrastructure, sectors critical to national security and economic stability. Exploitation could lead to unauthorized command execution, enabling attackers to disrupt services, intercept or manipulate sensitive communications, or pivot within networks to compromise additional assets. This could affect confidentiality by exposing sensitive data, integrity by altering system configurations or data, and availability by causing service outages. Given the remote, unauthenticated nature of the exploit, attackers could leverage this vulnerability to launch widespread attacks, potentially targeting critical infrastructure providers, ISPs, or enterprises relying on this hardware. The absence of vendor response and patches increases the window of exposure, elevating risk levels. European organizations with regulatory requirements for cybersecurity and data protection (e.g., GDPR) may face compliance challenges if exploited. The public availability of exploit code further heightens the threat landscape, necessitating immediate defensive measures.

1. Immediately restrict network access to the UTT HiPER 810 management interface, limiting it to trusted administrative IP addresses via firewall rules or VPNs. 2. Implement network segmentation to isolate affected devices from critical infrastructure and sensitive networks. 3. Monitor network traffic and device logs for unusual commands or access patterns indicative of exploitation attempts. 4. Disable or restrict remote management interfaces if not essential. 5. Employ intrusion detection/prevention systems (IDS/IPS) with signatures or heuristics targeting command injection attempts on /goform/formUser endpoints. 6. Maintain an inventory of devices running the affected firmware version and prioritize their remediation. 7. Engage with UTT or authorized vendors regularly to obtain patches or firmware updates once available. 8. Consider deploying host-based monitoring agents on devices if supported, to detect anomalous system calls or process executions. 9. Prepare incident response plans specific to this vulnerability, including rapid isolation and forensic analysis procedures. 10. Educate network administrators about the vulnerability and signs of exploitation to enhance detection capabilities.
