Comprehensive Technical Analysis of EUVD-2025-205861

1. Vulnerability Assessment and Severity Evaluation

Vulnerability Description: The vulnerability in Ksenia Security Lares 4.0 Home Automation version 1.6 involves the exposure of the alarm system PIN in the 'basisInfo' XML file after authentication. This critical flaw allows attackers to retrieve the PIN from the server response, bypassing security measures and disabling the alarm system without additional authentication.

Severity Evaluation: The vulnerability has a base score of 9.3 according to CVSS 4.0, indicating a critical severity level. The 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 highlights the following characteristics:

• Attack Vector (AV): Network (N)
• Attack Complexity (AC): Low (L)
• Authentication (AT): None (N)
• Privileges Required (PR): None (N)
• User Interaction (UI): None (N)
• Confidentiality (VC): High (H)
• Integrity (VI): High (H)
• Availability (VA): High (H)
• Scope Change (SC): None (N)
• Scope Integrity (SI): None (N)
• Scope Availability (SA): None (N)

The high scores for confidentiality, integrity, and availability indicate that the vulnerability can lead to significant security breaches, including unauthorized access and system compromise.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network-Based Attacks: Given the network attack vector (AV:N), attackers can exploit this vulnerability remotely over the network.
• Authentication Bypass: The low attack complexity (AC:L) and lack of required privileges (PR:N) or user interaction (UI:N) make it easier for attackers to exploit the vulnerability.

Exploitation Methods:

• PIN Extraction: Attackers can intercept the server response containing the 'basisInfo' XML file to extract the alarm system PIN.
• Alarm System Disablement: With the PIN, attackers can disable the alarm system, compromising the physical security of the premises.

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
