EUVD-2023-60237

Comprehensive Technical Analysis of EUVD-2023-60237

1. Vulnerability Assessment and Severity Evaluation

The vulnerability EUVD-2023-60237 affects Atom CMS version 2.0 and involves an unauthenticated SQL injection vulnerability. This flaw allows remote attackers to manipulate database queries through unvalidated parameters, specifically the 'id' parameter on the admin index page. The severity of this vulnerability is rated with a CVSS Base Score of 9.3, which is considered critical.

CVSS Vector Breakdown:

• AV:N (Network Vector): The vulnerability is exploitable over the network.
• AC:L (Low Attack Complexity): The attack requires low complexity to exploit.
• AT:N (No Authentication Required): No authentication is needed to exploit the vulnerability.
• PR:N (No Privileges Required): No privileges are required to exploit the vulnerability.
• UI:N (No User Interaction Required): No user interaction is required to exploit the vulnerability.
• VC:H (High Confidentiality Impact): The vulnerability has a high impact on confidentiality.
• VI:H (High Integrity Impact): The vulnerability has a high impact on integrity.
• VA:L (Low Availability Impact): The vulnerability has a low impact on availability.
• SC:N (No Security Controls): No security controls are in place to mitigate the vulnerability.
• SI:N (No Security Impact): The vulnerability does not affect the security impact.
• SA:N (No Security Assurance): The vulnerability does not affect the security assurance.

2. Potential Attack Vectors and Exploitation Methods

The primary attack vector is through the 'id' parameter on the admin index page of Atom CMS 2.0. Attackers can exploit this vulnerability by injecting malicious SQL code, leading to time-based blind SQL injection attacks. This type of attack allows attackers to extract sensitive information from the database, such as user credentials, configuration settings, and other critical data.

Exploitation Methods:

• Time-Based Blind SQL Injection: Attackers can use time-based delays to infer the structure and content of the database.
• Error-Based SQL Injection: Attackers can manipulate the SQL queries to generate error messages that reveal database information.
• Union-Based SQL Injection: Attackers can use UNION SQL queries to combine the results of two SELECT statements into a single result.

3. Affected Systems and Software Versions

The vulnerability specifically affects Atom CMS version 2.0. Other versions of Atom CMS may also be affected if they share the same codebase or have similar vulnerabilities. It is crucial to verify the impact on other versions and related software components.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Patching: Apply the latest security patches provided by the vendor (thedigicraft) to mitigate the vulnerability.
• Input Validation: Implement robust input validation and sanitization for all user inputs, especially the 'id' parameter.
• Parameterized Queries: Use parameterized queries or prepared statements to prevent SQL injection attacks.
• Web Application Firewall (WAF): Deploy a WAF to detect and block malicious SQL injection attempts.

Long-Term Mitigation:

• Regular Security Audits: Conduct regular security audits and code reviews to identify and fix vulnerabilities.
• Security Training: Provide security training for developers to ensure they follow best practices for secure coding.
• Monitoring and Logging: Implement comprehensive monitoring and logging to detect and respond to suspicious activities.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to organizations using Atom CMS 2.0, particularly within the European Union. The unauthenticated nature of the vulnerability means that any attacker with network access can exploit it, leading to potential data breaches and unauthorized access to sensitive information. This can result in financial losses, reputational damage, and legal consequences under regulations such as the General Data Protection Regulation (GDPR).

6. Technical Details for Security Professionals

Vulnerability Details:

• Vulnerable Parameter: 'id' parameter on the admin index page.
• Exploitation Technique: Time-based blind SQL injection.
• Impact: Unauthorized access to database information, including user credentials and configuration settings.

Detection and Response:

• Detection: Use intrusion detection systems (IDS) and intrusion prevention systems (IPS) to detect anomalous SQL queries.
• Response: Implement incident response procedures to contain and mitigate the impact of the vulnerability.
• Forensics: Conduct forensic analysis to determine the extent of the breach and identify compromised data.
