EUVD-2026-9375

Comprehensive Technical Analysis of EUVD-2026-9375

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2026-9375 pertains to the insecure storage of a hardcoded root password hash within the /root/anaconda-ks.cfg installation configuration file of the International Datacasting Corporation (IDC) SFX2100 SuperFlex Satellite Receiver. The password is susceptible to offline dictionary attacks using common wordlists such as rockyou.txt. The CVSS Base Score of 9.2 indicates a critical severity level, primarily due to the potential for privilege escalation to root access.

CVSS Vector Breakdown:

• Attack Vector (AV): Local (L) - The attacker must have local access to the system.
• Attack Complexity (AC): Low (L) - The attack requires minimal skill or resources.
• Authentication (AT): None (N) - No authentication is required to exploit the vulnerability.
• Privileges Required (PR): High (H) - The attacker must have high-level privileges to exploit the vulnerability.
• User Interaction (UI): None (N) - No user interaction is required.
• Scope (S): Changed (C) - The vulnerability affects a different security scope.
• Confidentiality Impact (C): High (H) - Complete loss of confidentiality.
• Integrity Impact (I): High (H) - Complete loss of integrity.
• Availability Impact (A): None (N) - No impact on availability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

1. Local Access: An attacker with physical or low-privileged access to the system can exploit this vulnerability.
2. Other Vulnerabilities: An attacker may exploit other vulnerabilities to gain initial low-privileged access.

Exploitation Methods:

1. Password Extraction: The attacker extracts the hardcoded root password hash from the /root/anaconda-ks.cfg file.
2. Dictionary Attack: The attacker uses a dictionary attack with the rockyou.txt wordlist to crack the password.
3. Privilege Escalation: Once the password is cracked, the attacker logs in as the root user, gaining full control over the system.

3. Affected Systems and Software Versions

The vulnerability affects the IDC SFX2100 SuperFlex Satellite Receiver, specifically the SFX2100 version. It is crucial to note that other versions of the SFX Series may also be affected if they share the same configuration file structure and password handling mechanisms.

4. Recommended Mitigation Strategies

1. Patch Management: Apply vendor-provided patches or updates that address this vulnerability.
2. Access Control: Implement strict access controls to limit physical and logical access to the system.
3. Monitoring: Deploy monitoring tools to detect unusual activities that may indicate an attempted exploitation.
4. Password Management: Ensure that all passwords, especially those with high privileges, are strong and not hardcoded.
5. Regular Audits: Conduct regular security audits to identify and mitigate similar vulnerabilities.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to the European cybersecurity landscape, particularly in sectors relying on satellite communication, such as broadcasting, telecommunications, and emergency services. Compromised satellite receivers could lead to unauthorized access, data breaches, and disruption of critical services. The high severity score underscores the need for immediate attention and mitigation efforts.

6. Technical Details for Security Professionals

Vulnerability Details:

• File Location: /root/anaconda-ks.cfg
• Password Storage: Hardcoded root password hash
• Password Strength: Highly insecure, susceptible to dictionary attacks
• Access Requirement: Local access with low-privileged user credentials

Exploitation Steps:

1. Gain Local Access: Obtain physical or low-privileged access to the system.
2. Extract Password Hash: Locate and extract the root password hash from the configuration file.
3. Crack Password: Use a dictionary attack with rockyou.txt to crack the password.
4. Escalate Privileges: Log in as the root user using the cracked password.

Detection and Response:

• File Integrity Monitoring: Monitor the integrity of critical configuration files.
• Log Analysis: Analyze system logs for unusual login attempts or privilege escalation activities.
• Incident Response: Have an incident response plan in place to quickly address any detected exploitation attempts.
