CVE-2024-39841 is a SQL Injection vulnerability identified in the service configuration functionality of Centreon Web, a popular IT infrastructure monitoring platform. The vulnerability affects versions 24.04.x before 24.04.3, 23.10.x before 23.10.13, 23.04.x before 23.04.19, and 22.10.x before 22.10.23. It allows an attacker with low privileges (PR:L) to remotely execute arbitrary SQL commands without requiring user interaction (UI:N). The vulnerability is exploitable over the network (AV:N) with low attack complexity (AC:L) and impacts the confidentiality, integrity, and availability of the system (C:H/I:H/A:H). The flaw stems from improper sanitization of user-supplied input in the service configuration module, enabling injection of malicious SQL code. Successful exploitation could lead to unauthorized data access, modification, or deletion, and potentially full system compromise. Although no exploits have been observed in the wild yet, the high CVSS score of 8.8 reflects the critical nature of this vulnerability. Centreon Web is widely deployed in enterprise and critical infrastructure environments for monitoring IT assets, making this vulnerability a significant risk. The vulnerability was reserved in June 2024 and published in August 2024, with patches released in the specified versions. However, no direct patch links were provided in the source information. The CWE-89 classification confirms the SQL Injection nature of the flaw.

The impact of CVE-2024-39841 is severe for organizations using affected versions of Centreon Web. Exploitation can lead to unauthorized disclosure of sensitive monitoring data, manipulation or deletion of configuration and monitoring information, and disruption of monitoring services. This can result in loss of visibility into IT infrastructure health, delayed incident response, and potential cascading failures in critical systems. Attackers could leverage the vulnerability to pivot within networks, escalate privileges, or deploy further malware. Given Centreon Web’s role in monitoring critical infrastructure and enterprise IT environments, the vulnerability poses a risk to operational continuity and data security. Organizations with exposed Centreon Web interfaces or insufficient network segmentation are particularly vulnerable. The absence of known exploits in the wild currently reduces immediate risk but does not diminish the urgency of remediation due to the ease of exploitation and high impact.

1. Immediately upgrade Centreon Web to the fixed versions: 24.04.3 or later, 23.10.13 or later, 23.04.19 or later, and 22.10.23 or later as applicable. 2. Restrict network access to the Centreon Web service configuration interface using firewalls, VPNs, or IP whitelisting to limit exposure. 3. Implement Web Application Firewalls (WAFs) with SQL Injection detection and prevention rules tailored to Centreon Web traffic. 4. Conduct thorough input validation and sanitization on all user inputs in custom configurations or integrations. 5. Monitor logs for unusual or suspicious SQL queries or errors indicative of injection attempts. 6. Employ network segmentation to isolate monitoring infrastructure from general user networks. 7. Regularly audit Centreon Web configurations and user privileges to minimize attack surface. 8. Prepare incident response plans specific to Centreon Web compromise scenarios. 9. Stay informed on vendor advisories and update promptly when new patches or mitigations are released.
