Comprehensive Technical Analysis of EUVD-2024-52813

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2024-52813 pertains to a SQL injection flaw in Centreon centreon-web, a popular network monitoring tool. The issue affects multiple versions of the software, specifically:

• Centreon centreon-web 24.10.x before 24.10.3
• Centreon centreon-web 24.04.x before 24.04.9
• Centreon centreon-web 23.10.x before 23.10.19
• Centreon centreon-web 23.04.x before 23.04.24

The vulnerability allows a user with high privileges to inject malicious SQL code into the form used to create virtual metrics. This can lead to unauthorized access to the database, data manipulation, and potential data exfiltration.

Severity Evaluation:

• Base Score: 9.1 (Critical)
• Base Score Version: 3.1
• Base Score Vector: CVSS:3.1/AC:L/AV:N/A:H/C:H/I:H/PR:H/S:C/UI:N

The CVSS score of 9.1 indicates a critical vulnerability due to the high impact on confidentiality, integrity, and availability. The attack complexity is low, and the attack vector is network-based, making it accessible remotely.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Exploitation: An attacker with high privileges can exploit this vulnerability over the network without requiring user interaction.
• Internal Threats: Insiders with elevated privileges could also exploit this vulnerability to gain unauthorized access to sensitive data.

Exploitation Methods:

• SQL Injection: The attacker can inject SQL commands into the form fields used to create virtual metrics. This can be done by crafting specific input that includes SQL commands, which the application then executes.
• Data Exfiltration: Once the SQL injection is successful, the attacker can extract sensitive information from the database.
• Data Manipulation: The attacker can alter database entries, leading to incorrect monitoring data and potential disruption of services.

3. Affected Systems and Software Versions

The vulnerability affects the following versions of Centreon centreon-web:

• 24.10.x before 24.10.3
• 24.04.x before 24.04.9
• 23.10.x before 23.10.19
• 23.04.x before 23.04.24

Organizations using these versions are at risk and should prioritize updating to the patched versions.

4. Recommended Mitigation Strategies

Immediate Actions:

• Update Software: Upgrade to the patched versions of Centreon centreon-web:
  • 24.10.3 or later
  • 24.04.9 or later
  • 23.10.19 or later
  • 23.04.24 or later
• Access Control: Restrict access to the virtual metrics creation form to trusted users only.
• Monitoring: Implement monitoring for unusual database queries and access patterns.

Long-Term Strategies:

• Regular Audits: Conduct regular security audits and vulnerability assessments.
• Training: Provide training for administrators on secure coding practices and SQL injection prevention.
• Patch Management: Establish a robust patch management process to ensure timely updates.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to organizations using Centreon for network monitoring, particularly those in critical infrastructure sectors such as healthcare, finance, and government. The potential for data breaches and service disruptions could have far-reaching consequences, including financial losses, reputational damage, and legal repercussions.

6. Technical Details for Security Professionals

SQL Injection Mechanism:

• The vulnerability arises from insufficient input validation in the form used to create virtual metrics.
• The attacker can inject SQL commands by including them in the input fields, which are then executed by the database.

Detection and Prevention:

• Input Validation: Ensure all user inputs are properly validated and sanitized.
• Parameterized Queries: Use parameterized queries or prepared statements to prevent SQL injection.
• Web Application Firewalls (WAF): Deploy WAFs to detect and block SQL injection attempts.
• Database Monitoring: Implement database activity monitoring to detect and respond to suspicious queries.
