EUVD-2025-203422

Comprehensive Technical Analysis of EUVD-2025-203422

1. Vulnerability Assessment and Severity Evaluation

The vulnerability in ReyeeOS 1.204.1614, identified as EUVD-2025-203422 (CVE-2023-53881), involves unencrypted CWMP (CPE WAN Management Protocol) communication. This flaw allows attackers to intercept and manipulate device communication through a man-in-the-middle (MitM) attack. The CVSS (Common Vulnerability Scoring System) base score of 9.2 indicates a critical severity level. The vector string CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N highlights the following:

• Attack Vector (AV): Network (N) - The vulnerability is exploitable over the network.
• Attack Complexity (AC): High (H) - The attack requires specific conditions or knowledge.
• Authentication (AT): None (N) - No authentication is required to exploit the vulnerability.
• Privileges Required (PR): None (N) - No special privileges are needed.
• User Interaction (UI): None (N) - No user interaction is required.
• Confidentiality Impact (VC): High (H) - There is a significant impact on confidentiality.
• Integrity Impact (VI): High (H) - There is a significant impact on integrity.
• Availability Impact (VA): High (H) - There is a significant impact on availability.

2. Potential Attack Vectors and Exploitation Methods

The primary attack vector is a MitM attack, where an attacker intercepts the unencrypted CWMP communication between the device and the CWMP server. Potential exploitation methods include:

• Intercepting Communication: Attackers can capture sensitive information transmitted over the network.
• Creating a Fake CWMP Server: Attackers can set up a rogue CWMP server to inject malicious commands into the device.
• Executing Arbitrary Commands: By exploiting the unprotected HTTP polling requests, attackers can execute arbitrary commands on the affected devices.

3. Affected Systems and Software Versions

The vulnerability specifically affects:

• Product: ReyeeOS
• Version: 1.204.1614
• Vendor: Ruijie

All devices running ReyeeOS 1.204.1614 are at risk.

4. Recommended Mitigation Strategies

To mitigate this vulnerability, the following strategies are recommended:

• Patch Management: Apply the latest security patches and updates provided by Ruijie.
• Encryption: Ensure that all CWMP communications are encrypted using secure protocols such as HTTPS.
• Network Segmentation: Implement network segmentation to isolate vulnerable devices from critical systems.
• Monitoring and Detection: Deploy intrusion detection systems (IDS) and intrusion prevention systems (IPS) to monitor for suspicious network activity.
• Access Control: Implement strict access controls and authentication mechanisms to limit unauthorized access.
