CVE-2025-4010 is a high-severity vulnerability affecting the Netcomm NTC 6200 and NWL 222 series devices. These devices expose a web interface used by operators for configuration and setup. The vulnerability stems from improper neutralization of special elements in commands (CWE-77), leading to command injection flaws. Multiple endpoints within the web interface are susceptible, allowing a remote authenticated attacker to inject arbitrary commands. Additionally, the presence of insecure hardcoded passwords exacerbates the risk by facilitating easier authentication. Exploitation of this vulnerability enables attackers to execute arbitrary code with elevated privileges on the affected devices, potentially compromising the device's confidentiality, integrity, and availability. The CVSS 4.0 score is 8.6 (high), reflecting the vulnerability's significant impact and relatively low attack complexity, requiring only low privileges and no user interaction. No patches are currently available, and no known exploits have been reported in the wild as of the publication date (June 2, 2025).

For European organizations, the impact of CVE-2025-4010 can be substantial, especially for those relying on Netcomm NTC 6200 or NWL 222 series devices in their network infrastructure. These devices are typically used in telecommunications or enterprise networking environments. Successful exploitation could lead to full device compromise, allowing attackers to manipulate network configurations, intercept or redirect traffic, or use the device as a foothold for lateral movement within the network. This could result in data breaches, service disruptions, or espionage activities. The elevated privileges gained by attackers increase the risk of persistent compromise and further exploitation. Given the critical role of network devices in operational continuity, affected organizations may face significant operational and reputational damage, as well as regulatory consequences under GDPR if personal data is impacted.

1. Immediate mitigation should focus on restricting access to the web interface to trusted management networks only, using network segmentation and firewall rules. 2. Change any default or hardcoded passwords on affected devices to strong, unique credentials to reduce the risk of unauthorized authentication. 3. Implement multi-factor authentication (MFA) if supported by the device to add an additional layer of security. 4. Monitor network traffic and device logs for unusual activity indicative of exploitation attempts, such as unexpected command executions or configuration changes. 5. Engage with Netcomm for any forthcoming patches or firmware updates addressing this vulnerability and prioritize their deployment once available. 6. If patching is delayed, consider temporary compensating controls such as disabling vulnerable web interface endpoints if feasible or using VPNs with strict access controls for management access. 7. Conduct regular security assessments and penetration testing focusing on network devices to identify and remediate similar vulnerabilities proactively.
