EUVD-2026-9369

Comprehensive Technical Analysis of EUVD-2026-9369

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2026-9369 is an OS Command Injection flaw in the web-based Traceroute diagnostic utility of the International Datacasting Corporation (IDC) SFX Series SuperFlex Satellite Receiver Web Management Interface version 101. This vulnerability allows an authenticated attacker to inject arbitrary shell metacharacters into the flags parameter, leading to the execution of arbitrary operating system commands with root privileges.

Severity Evaluation:

• Base Score: 9.3 (Critical)
• Base Score Version: 4.0
• Base Score Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:H/SI:H/SA:N

The high base score indicates a critical vulnerability due to the potential for complete system compromise, including confidentiality, integrity, and availability impacts. The attack vector is network-based, requiring low complexity and low privileges, but no user interaction.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Authenticated Access: An attacker must first gain authenticated access to the web management interface. This could be achieved through credential theft, brute-force attacks, or exploiting other vulnerabilities.
• Command Injection: Once authenticated, the attacker can inject shell metacharacters (e.g., |, ;, &&) into the flags parameter of the Traceroute utility to execute arbitrary commands.

Exploitation Methods:

• Payload Injection: The attacker can craft a payload that includes shell commands to be executed with root privileges. For example, traceroute -flags | rm -rf / could be used to delete critical system files.
• Persistent Access: The attacker could inject commands to create backdoors or install malware, ensuring persistent access to the system.

3. Affected Systems and Software Versions

Affected Systems:

• Product: SFX Series SuperFlex Satellite Receiver Web Management Interface
• Version: 101

Vendor:

• International Datacasting Corporation (IDC)

4. Recommended Mitigation Strategies

Immediate Actions:

• Patching: Apply the latest security patches provided by IDC to mitigate the vulnerability.
• Access Control: Implement strict access controls and multi-factor authentication (MFA) to prevent unauthorized access.
• Monitoring: Enhance monitoring and logging to detect and respond to suspicious activities.

Long-Term Strategies:

• Regular Audits: Conduct regular security audits and vulnerability assessments.
• User Training: Educate users on the importance of strong passwords and recognizing phishing attempts.
• Network Segmentation: Segment the network to limit the impact of a potential breach.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to European organizations using the affected IDC SFX Series SuperFlex Satellite Receivers, particularly in sectors relying on satellite communications such as broadcasting, telecommunications, and defense. The potential for unauthorized command execution with root privileges could lead to data breaches, service disruptions, and loss of critical infrastructure control.
