Comprehensive Technical Analysis of EUVD-2024-52191

1. Vulnerability Assessment and Severity Evaluation

The vulnerability EUVD-2024-52191, also known as CVE-2024-53923, affects multiple versions of Centreon Web, a popular network monitoring solution. The issue involves a SQL injection vulnerability in the media upload form, which can be exploited by users with high privileges. The CVSS (Common Vulnerability Scoring System) base score of 9.1 indicates a critical severity level. The CVSS vector CVSS:3.1/AC:L/AV:N/A:H/C:H/I:H/PR:H/S:C/UI:N breaks down as follows:

• Attack Complexity (AC): Low - The attack does not require special conditions.
• Attack Vector (AV): Network - The vulnerability is exploitable over the network.
• Availability Impact (A): High - The vulnerability can lead to significant disruption of services.
• Confidentiality Impact (C): High - The vulnerability can lead to unauthorized access to sensitive information.
• Integrity Impact (I): High - The vulnerability can lead to unauthorized modification of data.
• Privileges Required (PR): High - The attacker must have high privileges to exploit the vulnerability.
• Scope (S): Changed - The vulnerability affects resources beyond the security scope managed by the security authority.
• User Interaction (UI): None - No user interaction is required for the attack to succeed.

2. Potential Attack Vectors and Exploitation Methods

The primary attack vector is SQL injection, which can be executed through the media upload form. An attacker with high privileges can craft malicious SQL queries to manipulate the database. Potential exploitation methods include:

• Data Exfiltration: Extracting sensitive information from the database.
• Data Manipulation: Altering database records to disrupt services or gain unauthorized access.
• Privilege Escalation: Using the SQL injection to gain higher privileges within the system.
• Denial of Service (DoS): Executing SQL commands that disrupt the normal operation of the database.

3. Affected Systems and Software Versions

The vulnerability affects the following versions of Centreon Web:

• Centreon Web 24.10.x before 24.10.3
• Centreon Web 24.04.x before 24.04.9
• Centreon Web 23.10.x before 23.10.19
• Centreon Web 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

To mitigate the risk associated with this vulnerability, the following strategies are recommended:

• Update Software: Immediately update Centreon Web to the latest patched versions (24.10.3, 24.04.9, 23.10.19, 23.04.24 or later).
• Access Control: Restrict access to the media upload form to trusted users only.
• Input Validation: Implement robust input validation and sanitization mechanisms to prevent SQL injection attacks.
• Database Security: Use prepared statements and parameterized queries to interact with the database.
• Monitoring and Logging: Enhance monitoring and logging to detect and respond to suspicious activities.
• Regular Audits: Conduct regular security audits and vulnerability assessments.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to organizations using Centreon Web, particularly those in critical sectors such as healthcare, finance, and government. Given the critical nature of the vulnerability, it could lead to data breaches, service disruptions, and potential financial losses. The European cybersecurity landscape must prioritize timely patching and robust security measures to mitigate such risks.

6. Technical Details for Security Professionals
