EUVD-2025-36192

Comprehensive Technical Analysis of EUVD-2025-36192

1. Vulnerability Assessment and Severity Evaluation

The vulnerability identified in EUVD-2025-36192 affects MikroTik RouterOS v.7.14.2 and SwitchOS v.2.18, allowing a remote attacker to execute arbitrary code via the HTTP-only WebFig management component. The CVSS (Common Vulnerability Scoring System) base score of 10.0 indicates a critical severity level. The scoring vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:L breaks down as follows:

• AV:N (Attack Vector: Network): The vulnerability is exploitable over the network.
• AC:L (Attack Complexity: Low): The attack requires minimal skill or resources.
• PR:N (Privileges Required: None): No privileges are required to exploit the vulnerability.
• UI:N (User Interaction: None): No user interaction is required.
• S:C (Scope: Changed): The vulnerability affects a component that is outside the security scope of the vulnerable component.
• C:H (Confidentiality: High): There is a high impact on confidentiality.
• I:H (Integrity: High): There is a high impact on integrity.
• A:L (Availability: Low): There is a low impact on availability.

This high severity score underscores the critical nature of the vulnerability, necessitating immediate attention and mitigation.

2. Potential Attack Vectors and Exploitation Methods

The primary attack vector is through the HTTP-only WebFig management component, which is accessible over the network. Potential exploitation methods include:

• Remote Code Execution (RCE): An attacker could send specially crafted HTTP requests to the WebFig component, leading to arbitrary code execution on the affected device.
• Cross-Site Scripting (XSS): If the WebFig component does not properly sanitize user input, an attacker could inject malicious scripts that execute in the context of a user's browser.
• Command Injection: An attacker could inject malicious commands through the WebFig interface, leading to unauthorized actions on the device.

3. Affected Systems and Software Versions

The vulnerability affects the following systems and software versions:

• MikroTik RouterOS v.7.14.2
• MikroTik SwitchOS v.2.18

All devices running these versions of RouterOS and SwitchOS are potentially vulnerable.

4. Recommended Mitigation Strategies

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

• Patch Management: Immediately apply the latest patches and updates provided by MikroTik. Ensure that all devices are running the most recent versions of RouterOS and SwitchOS.
• Network Segmentation: Isolate the management interfaces of MikroTik devices from public networks to limit exposure.
• Access Control: Implement strict access controls and authentication mechanisms to restrict access to the WebFig management component.
• Monitoring and Logging: Enable comprehensive logging and monitoring to detect any suspicious activity or unauthorized access attempts.
• Firewall Rules: Configure firewall rules to block unauthorized access to the WebFig management component.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to the European cybersecurity landscape, particularly for organizations and individuals relying on MikroTik devices for network management. The potential for remote code execution and other exploits could lead to:

• Data Breaches: Unauthorized access to sensitive data.
• Network Compromise: Compromise of network infrastructure, leading to service disruptions and potential data loss.
• Compliance Issues: Non-compliance with data protection regulations such as GDPR, resulting in legal and financial repercussions.
