Comprehensive Technical Analysis of EUVD-2025-14179
1. Vulnerability Assessment and Severity Evaluation
The vulnerability EUVD-2025-14179 pertains to a stack overflow issue in the function.P2pListFilter of Tenda FH451 V1.0.0.9. The CVSS (Common Vulnerability Scoring System) base score of 9.8 indicates a critical severity level. The CVSS vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H breaks down as follows:
- Attack Vector (AV:N): Network, meaning the vulnerability is exploitable remotely over the network.
- Attack Complexity (AC:L): Low, indicating that the attack is relatively straightforward to execute.
- Privileges Required (PR:N): None, meaning no special privileges are needed to exploit the vulnerability.
- User Interaction (UI:N): None, indicating that no user interaction is required for the attack to succeed.
- Scope (S:U): Unchanged, meaning the vulnerability affects the same security scope.
- Confidentiality (C:H): High impact on confidentiality.
- Integrity (I:H): High impact on integrity.
- Availability (A:H): High impact on availability.
Given these metrics, the vulnerability poses a significant risk to the confidentiality, integrity, and availability of affected systems.
2. Potential Attack Vectors and Exploitation Methods
The stack overflow vulnerability in function.P2pListFilter can be exploited through several methods:
- Remote Code Execution (RCE): An attacker could send specially crafted network packets to the vulnerable function, causing a buffer overflow that allows for arbitrary code execution.
- Denial of Service (DoS): By exploiting the stack overflow, an attacker could crash the device, leading to 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:
- Device: Tenda FH451
- Firmware Version: V1.0.0.9
It is crucial to note that other versions of the firmware may also be affected if they share the same codebase.
4. Recommended Mitigation Strategies
To mitigate the risk associated with this vulnerability, the following strategies are recommended:
- Firmware Update: Immediately update the firmware to a version that addresses this vulnerability. If no update is available, contact the vendor for a patch.
- Network Segmentation: Isolate the affected devices on a separate network segment to limit the attack surface.
- Firewall Rules: Implement strict firewall rules to restrict access to the device from untrusted networks.
- Intrusion Detection Systems (IDS): Deploy IDS to monitor for suspicious network activity that may indicate an exploitation attempt.
- Regular Audits: Conduct regular security audits and vulnerability assessments to identify and address similar issues proactively.
5. Impact on European Cybersecurity Landscape
The vulnerability in Tenda FH451 V1.0.0.9 poses a significant threat to European cybersecurity, particularly in environments where these devices are widely deployed, such as small businesses, home networks, and public Wi-Fi hotspots. The potential for remote code execution and data exfiltration could lead to widespread breaches and loss of sensitive information. Organizations and individuals must prioritize updating their devices to mitigate this risk.
6. Technical Details for Security Professionals
For security professionals, the following technical details are pertinent:
- Vulnerability Type: Stack overflow in
function.P2pListFilter. - Exploitation: The vulnerability can be triggered by sending malformed network packets to the device.
- Detection: Monitor network traffic for unusual patterns that may indicate an exploitation attempt. Use tools like Wireshark to analyze suspicious packets.
- Mitigation: Ensure that all Tenda FH451 devices are updated to the latest firmware version. Implement network security measures to restrict access and detect potential attacks.
