EUVD-2025-10345

Comprehensive Technical Analysis of EUVD-2025-10345

1. Vulnerability Assessment and Severity Evaluation

The vulnerability identified in EUVD-2025-10345 affects multiple versions of the Industrial Edge Device Kit and related devices. The issue lies in the improper enforcement of user authentication on specific API endpoints when identity federation is used. This flaw allows an unauthenticated remote attacker to bypass authentication mechanisms and impersonate a legitimate user.

Severity Evaluation:

• CVSS Base Score: 9.8
• CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

The high base score indicates a critical vulnerability. The attack vector is network-based (AV:N), requires low complexity (AC:L), no privileges (PR:N), and no user interaction (UI:N). The impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H).

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network-Based Attack: The attacker can exploit the vulnerability remotely over the network.
• Identity Federation: The attack requires that identity federation is currently or has previously been used.

Exploitation Methods:

• Unauthenticated Access: The attacker can access specific API endpoints without proper authentication.
• User Impersonation: By exploiting the vulnerability, the attacker can impersonate a legitimate user, gaining unauthorized access to sensitive information and systems.

3. Affected Systems and Software Versions

The vulnerability affects a wide range of Industrial Edge Device Kit versions and related devices, including:

• Industrial Edge Device Kit - arm64: V1.17 (All versions), V1.18 (All versions), V1.19 (All versions), V1.20 (All versions < V1.20.2-1), V1.21 (All versions < V1.21.1-1)
• Industrial Edge Device Kit - x86-64: V1.17 (All versions), V1.18 (All versions), V1.19 (All versions), V1.20 (All versions < V1.20.2-1), V1.21 (All versions < V1.21.1-1)
• Industrial Edge Own Device (IEOD): All versions < V1.21.1-1-a
• Industrial Edge Virtual Device: All versions < V1.21.1-1-a
• SCALANCE LPE9413: All versions
• SIMATIC IPC Devices: BX-39A, BX-59A, IPC127E, IPC227E, IPC427E, IPC847E (All versions < V3.0)

4. Recommended Mitigation Strategies

Immediate Actions:

• Patch Management: Apply the latest patches and updates provided by Siemens for the affected versions.
• Access Control: Implement strict access controls and monitor API endpoints for unauthorized access.
• Network Segmentation: Segregate critical systems from the broader network to limit the attack surface.

Long-Term Strategies:

• Regular Audits: Conduct regular security audits and vulnerability assessments.
• User Education: Educate users about the risks of identity federation and the importance of strong authentication mechanisms.
• Incident Response Plan: Develop and maintain an incident response plan to quickly address any security breaches.
