The vulnerability EUVD-2025-37352, also known as CVE-2025-64388, is a Denial of Service (DoS) issue affecting the web server through specific requests to a particular protocol. The CVSS (Common Vulnerability Scoring System) base score of 9.2 indicates a critical severity level. The CVSS vector CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:H provides the following insights:

• Attack Vector (AV:N): The vulnerability can be exploited over the network.
• Attack Complexity (AC:L): The attack is of low complexity, meaning it does not require specialized conditions or knowledge.
• Authentication (AT:N): No authentication is required to exploit the vulnerability.
• Privileges Required (PR:N): No privileges are required to exploit the vulnerability.
• User Interaction (UI:N): No user interaction is required to exploit the vulnerability.
• Confidentiality (VC:N): There is no impact on the confidentiality of the system.
• Integrity (VI:N): There is no impact on the integrity of the system.
• Availability (VA:H): There is a high impact on the availability of the system, leading to a DoS condition.
• Scope Change (SC:N): The scope of the vulnerability does not change.
• Scope Integrity (SI:N): There is no impact on the integrity of the scope.
• Scope Availability (SA:H): There is a high impact on the availability within the scope.

2. Potential Attack Vectors and Exploitation Methods

The primary attack vector for this vulnerability is network-based. An attacker can send specifically crafted requests to the web server, exploiting the vulnerability and causing a DoS condition. The low complexity and lack of required authentication or user interaction make this vulnerability particularly dangerous, as it can be easily exploited by attackers with minimal resources.

Potential exploitation methods include:

• Automated Scripts: Attackers can use automated scripts to send malicious requests to the web server.
• Botnets: Utilizing botnets to amplify the attack and overwhelm the server.
• Manual Exploitation: Manually crafting and sending requests to the server to trigger the DoS condition.

3. Affected Systems and Software Versions

The vulnerability affects the product TCPRS1plus version 1.0.14, manufactured by Circutor. Organizations using this specific version of the product are at risk and should take immediate action to mitigate the vulnerability.

4. Recommended Mitigation Strategies

To mitigate the risk associated with EUVD-2025-37352, the following strategies are recommended:

• Patch Management: Apply the latest patches and updates provided by the vendor, Circutor. Ensure that the software is updated to a version that addresses this vulnerability.
• Network Security: Implement network security measures such as firewalls, intrusion detection systems (IDS), and intrusion prevention systems (IPS) to monitor and block malicious traffic.
• Rate Limiting: Implement rate limiting on the web server to prevent excessive requests from overwhelming the server.
• Access Control: Restrict access to the web server to trusted IP addresses and networks.
• Monitoring and Logging: Enhance monitoring and logging to detect and respond to suspicious activities promptly.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to European organizations using the affected product, particularly those in critical infrastructure sectors such as energy, manufacturing, and healthcare. A successful exploitation could lead to service disruptions, financial losses, and potential safety risks.
