CVE-2024-32010 is a vulnerability classified under CWE-732 (Incorrect Permission Assignment for Critical Resource) affecting Siemens Spectrum Power 4 software versions earlier than V4.70 SP12 Update 2. The core issue is that a credential file containing database access information is configured with overly permissive file system permissions, making it world-readable. This allows any local user or attacker with local access to read the file and extract database credentials. With these credentials, an attacker can authenticate as a privileged application user to the underlying database. This elevated access enables the attacker to execute arbitrary system commands via the database interface, potentially leading to complete system compromise, data exfiltration, or disruption of services. The vulnerability requires only low privileges (local access) and no user interaction, increasing its risk profile. The CVSS v3.1 score is 7.8 (high), reflecting the high impact on confidentiality, integrity, and availability, combined with low attack complexity and privileges required. Siemens has reserved the CVE and published the vulnerability details, but no patches or exploits are currently publicly available. Given Spectrum Power 4’s role in managing energy grid operations, exploitation could have severe consequences for critical infrastructure.

For European organizations, particularly those in the energy sector using Siemens Spectrum Power 4, this vulnerability poses a significant risk. Unauthorized extraction of database credentials can lead to unauthorized control over critical grid management systems, potentially causing operational disruptions, data breaches, or sabotage. The ability to execute system commands via the database further elevates the threat, enabling attackers to manipulate system configurations, disrupt services, or pivot to other network segments. Such impacts could affect grid stability, leading to power outages or safety hazards. Confidentiality breaches could expose sensitive operational data, while integrity violations could corrupt system states or data. Availability impacts could result in denial of service to critical energy infrastructure. Given the strategic importance of energy infrastructure in Europe and regulatory requirements for cybersecurity, this vulnerability could also lead to compliance violations and reputational damage.

European organizations should take immediate steps to mitigate this vulnerability. First, apply Siemens’ official patches or updates for Spectrum Power 4 as soon as they become available, specifically upgrading to version V4.70 SP12 Update 2 or later. Until patches are deployed, restrict file system permissions on credential files to limit access strictly to necessary service accounts, removing world-readable permissions. Implement strict access controls and monitoring on systems running Spectrum Power 4 to detect unauthorized local access attempts. Employ network segmentation to limit access to critical systems and databases. Use host-based intrusion detection systems (HIDS) to alert on suspicious file access or command executions. Regularly audit file permissions and system configurations to ensure compliance with security best practices. Additionally, conduct security awareness training for administrators to recognize and respond to potential exploitation attempts. Finally, maintain up-to-date backups and incident response plans tailored to critical infrastructure scenarios.
