EUVD-2025-204816

Comprehensive Technical Analysis of EUVD-2025-204816

1. Vulnerability Assessment and Severity Evaluation

The vulnerability EUVD-2025-204816 affects the Tenda WH450 router, specifically version 1.0.0.18. The issue resides in the /goform/NatStaticSetting file, where an unknown function is susceptible to a stack-based buffer overflow due to the manipulation of the page argument. This vulnerability is severe, with a CVSS base score of 9.3, indicating a critical risk. The high score is attributed to the following factors:

• Attack Vector (AV:N): The vulnerability can be exploited remotely over the network.
• Attack Complexity (AC:L): The attack requires low complexity.
• Privileges Required (PR:N): No privileges are required to exploit the vulnerability.
• User Interaction (UI:N): No user interaction is needed.
• Confidentiality (VC:H): High impact on confidentiality.
• Integrity (VI:H): High impact on integrity.
• Availability (VA:H): High impact on availability.

The exploit is publicly available, increasing the risk of widespread exploitation.

2. Potential Attack Vectors and Exploitation Methods

The primary attack vector is remote exploitation via network access. An attacker can send a specially crafted request to the /goform/NatStaticSetting endpoint, causing a stack-based buffer overflow. This can lead to arbitrary code execution, allowing the attacker to gain control over the device.

Potential exploitation methods include:

• Direct Network Attack: An attacker can exploit the vulnerability by sending malicious packets directly to the router.
• Phishing and Social Engineering: Attackers may trick users into visiting malicious websites that exploit the vulnerability.
• Botnets: Infected devices can be used to spread the exploit to other vulnerable routers, creating a botnet.

3. Affected Systems and Software Versions

The vulnerability specifically affects:

• Product: Tenda WH450
• Version: 1.0.0.18

Other versions of the Tenda WH450 and similar devices may also be affected, but this has not been confirmed. Users should verify the firmware version and apply updates as necessary.

4. Recommended Mitigation Strategies

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

• Firmware Update: Immediately update the firmware to the latest version provided by Tenda.
• Network Segmentation: Isolate the router from critical networks to limit the potential impact of an attack.
• Firewall Configuration: Implement strict firewall rules to block unauthorized access to the router.
• Monitoring and Logging: Enable logging and monitoring to detect any suspicious activity.
• User Education: Educate users about the risks of phishing and social engineering attacks.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to European cybersecurity, particularly for organizations and individuals using the Tenda WH450 router. The potential for remote exploitation and the high impact on confidentiality, integrity, and availability make it a critical concern. Organizations should prioritize patching and implementing mitigation strategies to protect against potential attacks.
