EUVD-2025-35658

Comprehensive Technical Analysis of EUVD-2025-35658

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2025-35658 pertains to outdated and vulnerable UI dependencies in Azure Access Technology's BLU-IC2 and BLU-IC4 products, affecting versions up to 1.19.5. The CVSS (Common Vulnerability Scoring System) base score of 10.0 indicates a critical severity level. This score is derived from the following vector string:

• CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H

This vector string signifies:

• AV:N (Attack Vector: Network) - The vulnerability can be exploited remotely over the network.
• AC:L (Attack Complexity: Low) - The attack requires minimal skill or resources.
• AT:N (Authentication: None) - No authentication is required to exploit the vulnerability.
• PR:N (Privileges Required: None) - No special privileges are needed.
• UI:N (User Interaction: None) - No user interaction is required.
• VC:H (Vulnerability Confidentiality: High) - The vulnerability has a high impact on confidentiality.
• VI:H (Vulnerability Integrity: High) - The vulnerability has a high impact on integrity.
• VA:H (Vulnerability Availability: High) - The vulnerability has a high impact on availability.
• SC:H (Scope Change: High) - The vulnerability can affect components beyond its security scope.
• SI:H (Scope Integrity: High) - The vulnerability has a high impact on the integrity of the affected scope.
• SA:H (Scope Availability: High) - The vulnerability has a high impact on the availability of the affected scope.

Given the critical severity and the high impact on confidentiality, integrity, and availability, this vulnerability poses a significant risk to affected systems.

2. Potential Attack Vectors and Exploitation Methods

The primary attack vector is network-based, meaning attackers can exploit the vulnerability remotely. Potential exploitation methods include:

• Remote Code Execution (RCE): Attackers could exploit the outdated UI dependencies to execute arbitrary code on the affected systems.
• Data Exfiltration: Sensitive data could be accessed or stolen due to the high impact on confidentiality.
• Service Disruption: The high impact on availability suggests that attackers could cause denial-of-service (DoS) conditions, rendering the affected systems unusable.
• Unauthorized Access: The high impact on integrity indicates that attackers could modify data or system configurations without authorization.

3. Affected Systems and Software Versions

The vulnerability affects the following systems and software versions:

• BLU-IC2: Versions up to and including 1.19.5
• BLU-IC4: Versions up to and including 1.19.5

These products are developed by Azure Access Technology, and organizations using these versions are at risk.

4. Recommended Mitigation Strategies

To mitigate the risk associated with this vulnerability, the following strategies are recommended:

• Update Software: Immediately update to the latest version of BLU-IC2 and BLU-IC4 that addresses this vulnerability.
• Network Segmentation: Implement network segmentation to isolate critical systems and reduce the attack surface.
• Firewall Rules: Configure firewalls to restrict access to the affected systems, allowing only trusted sources.
• Intrusion Detection Systems (IDS): Deploy IDS to monitor for suspicious activities and potential exploitation attempts.
• Regular Audits: Conduct regular security audits and vulnerability assessments to identify and address similar issues proactively.
• Patch Management: Establish a robust patch management process to ensure timely updates and patches are applied.
