Comprehensive Technical Analysis of EUVD-2025-204684
1. Vulnerability Assessment and Severity Evaluation
The vulnerability EUVD-2025-204684 affects the Tenda WH450 router, specifically version 1.0.0.18. The issue resides in the HTTP Request Handler component, particularly in the file /goform/L7Im. The vulnerability is a stack-based buffer overflow, which can be triggered by manipulating the page argument. This vulnerability is severe, with a CVSS base score of 9.3, indicating a critical risk. The high score is due 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 to execute.
- Privileges Required (PR:N): No privileges are required to exploit the vulnerability.
- User Interaction (UI:N): No user interaction is required.
- Confidentiality (VC:H), Integrity (VI:H), and Availability (VA:H): All three are highly impacted.
2. Potential Attack Vectors and Exploitation Methods
The primary attack vector is remote exploitation via the HTTP Request Handler. An attacker can send a specially crafted HTTP request to the vulnerable endpoint /goform/L7Im, manipulating the page argument to cause 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:
- Remote Code Execution (RCE): By exploiting the buffer overflow, an attacker can execute arbitrary code on the device.
- Denial of Service (DoS): The attacker can crash the device, making it unavailable to legitimate users.
- Data Exfiltration: The attacker can potentially extract sensitive information from the device.
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 from Tenda may also be affected, but this has not been confirmed. Users and administrators 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 a version that addresses this vulnerability. If no update is available, contact Tenda for guidance.
- Network Segmentation: Isolate the affected devices on a separate network segment to limit potential attack vectors.
- Firewall Rules: Implement strict firewall rules to restrict access to the HTTP Request Handler.
- Monitoring and Logging: Enable comprehensive logging and monitoring to detect any suspicious activity targeting the vulnerable endpoint.
- Intrusion Detection Systems (IDS): Deploy IDS to detect and alert on any attempts to exploit this vulnerability.
5. Impact on European Cybersecurity Landscape
The vulnerability poses a significant risk to the European cybersecurity landscape, particularly for organizations and individuals using the Tenda WH450 router. Given the widespread use of routers in both home and enterprise environments, the potential for large-scale exploitation is high. This vulnerability underscores the importance of timely patch management and the need for robust security measures to protect network devices.
