1. Vulnerability Assessment and Severity Evaluation
The vulnerability identified in Shiguangwu sgwbox N3 2.0.25 involves a command injection flaw in the /usr/sbin/http_eshell_server file of the NETREBOOT Interface component. This vulnerability allows an attacker to execute arbitrary commands on the affected system remotely. The CVSS (Common Vulnerability Scoring System) base score of 9.3 indicates a critical severity level. The scoring vector 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-based attack.
- Attack Complexity (AC:L): Low complexity required to exploit.
- Authentication (AT:N): No authentication required.
- Privileges Required (PR:N): No privileges required.
- User Interaction (UI:N): No user interaction required.
- Confidentiality Impact (VC:H): High impact on confidentiality.
- Integrity Impact (VI:H): High impact on integrity.
- Availability Impact (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 command injection, which can be exploited through:
- Network-Based Attacks: An attacker can send specially crafted HTTP requests to the
http_eshell_serverto inject and execute arbitrary commands. - Publicly Available Exploits: Given that the exploit is publicly available, attackers can easily find and use existing proof-of-concept code to launch attacks.
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
To mitigate the risk associated with this vulnerability, the following strategies are recommended:
- Patch Management: Apply the latest patches and updates provided by the vendor. If the vendor has not responded, consider alternative mitigation strategies.
- Network Segmentation: Isolate the affected systems from the broader network to limit the attack surface.
- Firewall Rules: Implement strict firewall rules to restrict access to the
http_eshell_server. - Intrusion Detection/Prevention Systems (IDS/IPS): Deploy IDS/IPS to monitor and block suspicious network traffic 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 presence of this vulnerability in a widely used product like Shiguangwu sgwbox N3 poses significant risks to European organizations, particularly those in sectors relying on network-attached storage (NAS) solutions. The potential for remote command injection can lead to data breaches, unauthorized access, and service disruptions, impacting the confidentiality, integrity, and availability of critical data.
6. Technical Details for Security Professionals
- Vulnerable Component:
/usr/sbin/http_eshell_server - Exploit Type: Command Injection
