CVE-2025-64444 is an OS command injection vulnerability identified in Sony Network Communications Inc.'s NCP-HG100 Cellular model firmware versions 1.4.48.16 and earlier. The vulnerability stems from improper neutralization of special characters within OS commands constructed by the device's management interface. When an attacker authenticates to the management page, they can inject malicious OS commands that the device executes with root privileges, effectively granting full control over the device. This type of vulnerability allows attackers to compromise device confidentiality, integrity, and availability by executing arbitrary commands, potentially leading to data theft, device manipulation, or denial of service. The vulnerability requires valid credentials to access the management interface, which raises the bar for exploitation but does not eliminate risk, especially if credential theft or weak authentication mechanisms exist. The CVSS v3.0 score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H) indicates a network attack vector with low complexity but requiring high privileges (authenticated user), no user interaction, and high impact on confidentiality, integrity, and availability. No public exploits have been reported yet, but the vulnerability is published and known since November 2025. The lack of available patches at the time of disclosure increases the urgency for defensive measures. The affected product is used in cellular network communications, which may be part of critical infrastructure or enterprise network environments.

For European organizations, the impact of CVE-2025-64444 can be significant, especially for those relying on Sony NCP-HG100 devices within their cellular or network communication infrastructure. Successful exploitation could lead to complete device compromise, enabling attackers to intercept sensitive communications, disrupt network services, or pivot to other internal systems. This can result in data breaches, operational downtime, and loss of trust. Given the root-level access gained, attackers could install persistent backdoors or manipulate device configurations, complicating incident response. The vulnerability's requirement for authentication means that organizations with weak credential management or exposed management interfaces are at higher risk. The impact is particularly critical for sectors such as telecommunications, government, and critical infrastructure operators in Europe, where network reliability and data confidentiality are paramount. Additionally, disruption in cellular network components could affect emergency services and business continuity.

1. Immediately restrict access to the management interface of NCP-HG100 devices to trusted networks only, using network segmentation and firewall rules. 2. Enforce strong authentication policies, including complex passwords and multi-factor authentication, to reduce the risk of credential compromise. 3. Monitor management interface access logs for unusual login attempts or command execution patterns indicative of exploitation attempts. 4. Coordinate with Sony Network Communications Inc. for timely firmware updates and apply patches as soon as they become available. 5. If patching is delayed, consider temporary mitigations such as disabling remote management or using VPNs for management access to reduce exposure. 6. Conduct regular security audits and vulnerability assessments on network devices to identify and remediate similar issues proactively. 7. Educate network administrators on the risks of OS command injection and the importance of credential security. 8. Implement intrusion detection/prevention systems (IDS/IPS) tuned to detect anomalous command injection attempts targeting these devices.
