EUVD-2025-7276

Comprehensive Technical Analysis of EUVD-2025-7276

1. Vulnerability Assessment and Severity Evaluation

The vulnerability EUVD-2025-7276, classified as critical, affects the D-Link DAP-1620 1.03 device. The issue resides in the set_ws_action function within the /dws/api/ file of the Path Handler component. This vulnerability results in a heap-based buffer overflow, which can be exploited remotely. The CVSS Base Score of 9.3 indicates a high severity, reflecting the potential for significant impact if exploited.

CVSS Vector Breakdown:

• AV:N (Network Vector): The vulnerability can be exploited over the network.
• AC:L (Low Complexity): The attack requires low skill or resources to exploit.
• AT:N (No Authentication): No authentication is required to exploit the vulnerability.
• PR:N (No Privileges Required): No privileges are required to exploit the vulnerability.
• UI:N (No User Interaction): No user interaction is required to exploit the vulnerability.
• VC:H (High Confidentiality Impact): Successful exploitation can result in high confidentiality impact.
• VI:H (High Integrity Impact): Successful exploitation can result in high integrity impact.
• VA:H (High Availability Impact): Successful exploitation can result in high availability impact.
• SC:N (No Scope Change): The vulnerability does not change the security scope.
• SI:N (No Scope Integrity): The vulnerability does not affect the integrity of the security scope.
• SA:N (No Scope Availability): The vulnerability does not affect the availability of the security scope.

2. Potential Attack Vectors and Exploitation Methods

Given the nature of the vulnerability, potential attack vectors include:

• Remote Code Execution (RCE): An attacker could send specially crafted network packets to the vulnerable function, leading to a heap-based buffer overflow. This could allow the attacker to execute arbitrary code on the affected device.
• Denial of Service (DoS): The buffer overflow could also be used to crash the device, resulting in a denial of service.
• Data Exfiltration: If the attacker gains control over the device, they could exfiltrate sensitive data, such as network configurations or user credentials.

3. Affected Systems and Software Versions

The vulnerability specifically affects the D-Link DAP-1620 device running firmware version 1.03. It is important to note that this version is no longer supported by the manufacturer, which increases the risk as no official patches will be provided.

4. Recommended Mitigation Strategies

Given that the affected firmware version is no longer supported, the following mitigation strategies are recommended:

• Upgrade to Supported Versions: If possible, upgrade to a supported firmware version or a newer model that is still receiving security updates.
• Network Segmentation: Isolate the affected device on a separate network segment to limit potential attack vectors.
• Firewall Rules: Implement strict firewall rules to restrict access to the device, allowing only trusted IP addresses.
• Monitoring and Logging: Enhance monitoring and logging to detect any suspicious activity targeting the device.
• Intrusion Detection Systems (IDS): Deploy IDS to identify and alert on any unusual network traffic that may indicate an exploitation attempt.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to European organizations and individuals using the affected D-Link DAP-1620 device. The potential for remote exploitation and the high impact on confidentiality, integrity, and availability make it a critical concern. Organizations should prioritize identifying and mitigating this vulnerability to prevent potential breaches and ensure compliance with relevant cybersecurity regulations such as GDPR.
