Comprehensive Technical Analysis of EUVD-2025-205864

1. Vulnerability Assessment and Severity Evaluation

Vulnerability Description: The Ksenia Security Lares 4.0 Home Automation system version 1.6 contains a default credentials vulnerability. This flaw allows unauthorized attackers to gain administrative access using the weak default administrative credentials, thereby obtaining full control of the home automation system.

Severity Evaluation: The vulnerability has a CVSS (Common Vulnerability Scoring System) base score of 9.3, which is classified as critical. The CVSS vector string CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N indicates the following:

• Attack Vector (AV): Network (N) - The vulnerability is exploitable over the network.
• Attack Complexity (AC): Low (L) - The attack requires low complexity.
• Authentication (AT): None (N) - No authentication is required to exploit the vulnerability.
• Privileges Required (PR): None (N) - No privileges are required to exploit the vulnerability.
• User Interaction (UI): None (N) - No user interaction is required to exploit the vulnerability.
• Confidentiality (VC): High (H) - The vulnerability has a high impact on confidentiality.
• Integrity (VI): High (H) - The vulnerability has a high impact on integrity.
• Availability (VA): High (H) - The vulnerability has a high impact on availability.
• Scope (SC): Not Changed (N) - The vulnerability does not change the security scope.
• Scope Impact (SI): Not Changed (N) - The vulnerability does not change the impact on the security scope.
• Scope Availability (SA): Not Changed (N) - The vulnerability does not change the availability within the security scope.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network-Based Attacks: Attackers can exploit the vulnerability over the network, making it accessible to remote attackers.
• Default Credentials: The use of default administrative credentials allows attackers to gain unauthorized access without needing to perform complex attacks.

Exploitation Methods:

• Credential Stuffing: Attackers can use known default credentials to log in to the system.
• Automated Scanning: Attackers can use automated tools to scan for devices with default credentials and exploit them en masse.
• Man-in-the-Middle (MitM) Attacks: If the system uses unencrypted communication, attackers can intercept credentials and use them to gain access.

3. Affected Systems and Software Versions

Affected Systems:

• Ksenia Security Lares 4.0 Home Automation version 1.6
• Ksenia Security Lares 4.0 Home Automation version 1.0.0.15

Vendor:

• Ksenia Security S.p.A.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Change Default Credentials: Immediately change the default administrative credentials to strong, unique passwords.
• Network Segmentation: Isolate the home automation system from the public internet to limit exposure.
• Patch Management: Apply any available patches or updates from the vendor to mitigate the vulnerability.

Long-Term Mitigation:

• Regular Audits: Conduct regular security audits to identify and remediate vulnerabilities.
• User Education: Educate users on the importance of changing default credentials and using strong passwords.
• Monitoring: Implement continuous monitoring to detect and respond to unauthorized access attempts.

5. Impact on European Cybersecurity Landscape

Regulatory Compliance:

• GDPR: The vulnerability could lead to unauthorized access to personal data, potentially violating GDPR regulations.
• NIS Directive: Organizations operating critical infrastructure may need to comply with the NIS Directive, which requires robust cybersecurity measures.
