CVE-2024-8877 identifies a SQL Injection vulnerability in the Riello Netman 204 device, specifically affecting its SQLite database that stores measurement data. The root cause is improper neutralization of special elements in SQL commands, allowing an unauthenticated remote attacker to inject malicious SQL statements. This vulnerability affects versions of Netman 204 up to 4.05. The SQLite database is used internally to log measurement data, and exploitation could allow attackers to read or manipulate this data, potentially leading to data leakage or corruption. The CVSS 4.0 score is 6.9 (medium severity), reflecting the network attack vector, no required privileges or user interaction, and limited impact on confidentiality and integrity. The vulnerability does not affect availability or require authentication, increasing the risk of exploitation. No public exploits are known at this time, but the ease of exploitation and the critical nature of measurement data in energy management systems make this a significant concern. The vulnerability was reserved and published in September 2024 by CyberDanube. No patches are currently linked, indicating that organizations must monitor vendor updates closely. The attack surface includes any exposed Netman 204 management interfaces connected to untrusted networks. Given the role of Riello Netman 204 in energy and industrial monitoring, exploitation could disrupt data accuracy and operational decisions.

For European organizations, the impact of CVE-2024-8877 could be significant, especially in sectors relying on accurate energy measurement and monitoring such as utilities, manufacturing, and critical infrastructure. Successful exploitation could compromise the integrity and confidentiality of measurement data, leading to incorrect energy usage reporting, billing errors, or operational mismanagement. While availability is not directly affected, corrupted or manipulated data could indirectly cause operational disruptions or trigger false alarms. The vulnerability's network accessibility and lack of required authentication increase the risk of remote attacks, potentially by cybercriminals or state-sponsored actors targeting energy infrastructure. This could undermine trust in energy management systems and complicate compliance with European regulations on data integrity and critical infrastructure protection. Organizations may face financial losses, reputational damage, and regulatory penalties if the vulnerability is exploited. The absence of known exploits currently provides a window for proactive mitigation.

1. Monitor Riello's official channels for patches addressing CVE-2024-8877 and apply them promptly once available. 2. Restrict network access to Netman 204 management interfaces by implementing strict firewall rules and network segmentation, limiting exposure to trusted internal networks only. 3. Employ intrusion detection and prevention systems (IDS/IPS) to monitor for suspicious SQL injection patterns targeting Netman 204 devices. 4. Where possible, implement application-layer input validation or filtering to sanitize inputs before they reach the SQLite database. 5. Conduct regular security audits and vulnerability assessments on energy management systems to identify and remediate similar injection flaws. 6. Educate operational technology (OT) and IT teams about the risks of SQL injection in industrial devices and enforce secure configuration baselines. 7. Consider deploying network anomaly detection tools specialized for industrial control systems to detect unusual database queries or commands. 8. Maintain up-to-date asset inventories to quickly identify affected Netman 204 devices and prioritize remediation efforts. These steps go beyond generic advice by focusing on network-level protections, monitoring, and operational awareness specific to the affected product and its deployment context.
