Comprehensive Technical Analysis of EUVD-2025-204386
1. Vulnerability Assessment and Severity Evaluation
The vulnerability identified in Tenda WH450 1.0.0.18 involves a stack-based buffer overflow in the HTTP Request Handler component, specifically within the /goform/onSSIDChange file. This vulnerability is triggered by manipulating the ssid_index argument, which can be exploited remotely. The CVSS base score of 9.3 indicates a critical severity level. The vector string CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P highlights the following:
- Attack Vector (AV:N): Network, meaning the vulnerability can be exploited remotely.
- Attack Complexity (AC:L): Low, indicating that the attack is relatively easy to execute.
- Authentication (AT:N): None, meaning no authentication is required to exploit the vulnerability.
- Privileges Required (PR:N): None, indicating that no special privileges are needed.
- User Interaction (UI:N): None, meaning no user interaction is required.
- Confidentiality (VC:H): High impact on confidentiality.
- Integrity (VI:H): High impact on integrity.
- Availability (VA:H): High impact on availability.
- Exploit Code Maturity (E:P): Proof-of-concept code is available.
2. Potential Attack Vectors and Exploitation Methods
The primary attack vector is remote exploitation via network access. An attacker can send a specially crafted HTTP request to the vulnerable component, manipulating the ssid_index 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 buffer overflow can cause the device to crash, leading to a denial of service.
- Data Exfiltration: The attacker can potentially exfiltrate sensitive data from the device.
3. Affected Systems and Software Versions
The affected system is the Tenda WH450 router running firmware version 1.0.0.18. It is crucial to note that other versions of the firmware may also be vulnerable if they share the same codebase.
4. Recommended Mitigation Strategies
To mitigate this vulnerability, the following strategies are recommended:
- Firmware Update: Immediately update the firmware to a version that addresses this vulnerability.
- Network Segmentation: Isolate the affected devices from critical networks to limit potential damage.
- Firewall Rules: Implement strict firewall rules to restrict access to the vulnerable component.
- Intrusion Detection Systems (IDS): Deploy IDS to monitor for suspicious network activity targeting the vulnerable component.
- Regular Audits: Conduct regular security audits and vulnerability assessments to identify and address similar issues.
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 high impact on confidentiality, integrity, and availability makes it a critical concern. Organizations should prioritize patching and mitigation efforts to prevent potential breaches and data exfiltration.
