EUVD-2025-10329

Comprehensive Technical Analysis of EUVD-2025-10329

1. Vulnerability Assessment and Severity Evaluation

The vulnerability identified in the SENTRON 7KT PAC1260 Data Manager (all versions) involves hardcoded credentials for remote access to the device operating system with root privileges. This vulnerability is particularly severe due to the following factors:

• Base Score: 10.0 (Critical)
• Base Score Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H
  • Attack Vector (AV:N): Network
  • Attack Complexity (AC:L): Low
  • Privileges Required (PR:N): None
  • User Interaction (UI:N): None
  • Scope (S:C): Changed
  • Confidentiality (C:H): High
  • Integrity (I:H): High
  • Availability (A:H): High

The high severity score indicates that this vulnerability poses a critical risk to the affected systems. The combination of network accessibility, low attack complexity, and the absence of required privileges or user interaction makes it highly exploitable.

2. Potential Attack Vectors and Exploitation Methods

• Remote Access: Attackers can exploit this vulnerability remotely over the network.
• SSH Service: The vulnerability requires the SSH service to be enabled, which can be achieved through the exploitation of another vulnerability (CVE-2024-41793).
• Hardcoded Credentials: Knowledge of the hardcoded credentials allows attackers to gain root access to the device operating system.
• Automated Scanning: Attackers may use automated scanning tools to identify devices with the SSH service enabled and attempt to use the hardcoded credentials for access.

3. Affected Systems and Software Versions

• Product: SENTRON 7KT PAC1260 Data Manager
• Versions: All versions

This indicates that all deployed instances of the SENTRON 7KT PAC1260 Data Manager are vulnerable unless specific mitigations have been applied.

4. Recommended Mitigation Strategies

• Disable SSH Service: Immediately disable the SSH service on all affected devices to prevent remote access.
• Network Segmentation: Implement network segmentation to isolate critical systems and reduce the attack surface.
• Credential Management: Change default credentials and implement strong, unique passwords for all devices.
• Patch Management: Apply vendor-provided patches and updates as soon as they become available.
• Monitoring and Logging: Enhance monitoring and logging to detect any unauthorized access attempts.
• Access Control: Implement strict access control policies to limit who can access and configure the devices.

5. Impact on European Cybersecurity Landscape

The vulnerability in the SENTRON 7KT PAC1260 Data Manager poses a significant risk to European critical infrastructure, particularly in sectors where Siemens products are widely used, such as energy, manufacturing, and healthcare. The potential for unauthenticated remote attackers to gain full control of these devices could lead to:

• Data Breaches: Unauthorized access to sensitive data.
• Operational Disruptions: Compromise of critical operations leading to downtime and financial losses.
• Safety Risks: Potential safety hazards in industrial environments.
• Regulatory Compliance: Non-compliance with European cybersecurity regulations and standards.
