Comprehensive Technical Analysis of EUVD-2025-203336
1. Vulnerability Assessment and Severity Evaluation
The vulnerability EUVD-2025-203336, also known as CVE-2025-14707, affects the Shiguangwu sgwbox N3 version 2.0.25. The flaw resides in the /usr/sbin/http_eshell_server file of the DOCKER Feature component, allowing for command injection through manipulation of the params argument. The vulnerability has a high base score of 9.3 according to CVSS 4.0, indicating 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 characteristics:
- Attack Vector (AV:N): Network, meaning the vulnerability can be exploited remotely.
- Attack Complexity (AC:L): Low, indicating that the attack is relatively straightforward 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.
- Scope Change (SC:N): No change in security scope.
- Scope Integrity (SI:N): No impact on scope integrity.
- Scope Availability (SA:N): No impact on scope 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 command injection through the manipulation of the params argument in the http_eshell_server file. An attacker can craft a malicious input to execute arbitrary commands on the affected system. Given the low attack complexity and the availability of proof-of-concept code, this vulnerability can be easily exploited by attackers with basic knowledge of command injection techniques.
3. Affected Systems and Software Versions
The vulnerability specifically affects:
- Product: Shiguangwu sgwbox N3
- Version: 2.0.25
Other versions of the sgwbox N3 may also be affected, but this has not been confirmed. Organizations using this product should verify the version in use and apply appropriate mitigations.
4. Recommended Mitigation Strategies
- Patch Management: Immediately apply any available patches or updates from the vendor. If no patch is available, consider upgrading to a newer, unaffected version if possible.
- Network Segmentation: Isolate the affected systems from the broader network to limit the attack surface.
- Input Validation: Implement strict input validation and sanitization for all user inputs, especially those related to the
paramsargument. - Monitoring and Logging: Enhance monitoring and logging to detect any suspicious activities or attempts to exploit the vulnerability.
- Access Controls: Restrict access to the
http_eshell_serverto only trusted and necessary users and systems. - Intrusion Detection/Prevention Systems (IDPS): Deploy IDPS to detect and prevent command injection attempts.
5. Impact on European Cybersecurity Landscape
The vulnerability poses a significant risk to organizations within the European Union that use the affected Shiguangwu sgwbox N3. Given the high base score and the potential for remote exploitation, this vulnerability could lead to widespread data breaches, system compromises, and service disruptions. The availability of proof-of-concept code increases the likelihood of exploitation, making it a critical concern for European cybersecurity authorities and organizations.
6. Technical Details for Security Professionals
- Vulnerable Component:
/usr/sbin/http_eshell_server - Affected Function: Unknown function within the
http_eshell_server - Exploitation Method: Command injection through manipulation of the
paramsargument - Detection: Monitor for unusual command execution patterns and network traffic anomalies.
- Mitigation: Implement input validation, network segmentation, and access controls. Apply patches as soon as they are available.
Conclusion
EUVD-2025-203336 represents a critical vulnerability that requires immediate attention from cybersecurity professionals. Organizations should prioritize patching affected systems, implementing robust input validation, and enhancing monitoring and access controls to mitigate the risk of exploitation.
