CVE-2024-39843 is a SQL injection vulnerability identified in Centreon version 24.04.2, a widely used IT infrastructure monitoring platform. The flaw exists in the create user form inputs, where insufficient input validation allows a remote attacker with high privileges to inject and execute arbitrary SQL commands against the backend database. This vulnerability falls under CWE-89, indicating classic SQL injection issues. The attack vector is network-based (AV:N), with low attack complexity (AC:L), but requires the attacker to already possess high privileges (PR:H) and does not require user interaction (UI:N). The scope is unchanged (S:U), meaning the impact is confined to the vulnerable component. The vulnerability impacts confidentiality and integrity heavily (C:H/I:H) and availability to a lesser extent (A:L). Exploiting this vulnerability could allow an attacker to manipulate user accounts, extract sensitive monitoring data, or alter configurations, potentially undermining the integrity of the monitoring system and the security posture of the monitored infrastructure. No patches or known exploits have been reported as of the publication date, but the presence of this vulnerability necessitates immediate attention from organizations using Centreon 24.04.2. Given the nature of Centreon as a critical monitoring tool, exploitation could have cascading effects on operational security and incident response capabilities.

The impact of CVE-2024-39843 is significant for organizations relying on Centreon 24.04.2 for IT infrastructure monitoring. Successful exploitation could lead to unauthorized access to sensitive monitoring data, manipulation or creation of user accounts, and potential disruption of monitoring services. This could result in loss of confidentiality of operational data, integrity breaches where attackers alter monitoring configurations or data, and limited availability impact due to potential database corruption or service disruption. Such compromises could delay detection of other attacks or system failures, increasing overall organizational risk. The requirement for high privileges limits the attack surface but also indicates that insider threats or compromised high-privilege accounts could be leveraged. Organizations in sectors with critical infrastructure, such as energy, telecommunications, finance, and government, may face heightened risks due to the reliance on Centreon for real-time monitoring and alerting.

1. Immediately restrict and audit high-privileged user accounts in Centreon to minimize the risk of exploitation. 2. Implement strict input validation and sanitization on all user input fields, especially the create user form, to prevent SQL injection. 3. Monitor database logs and application logs for unusual or suspicious SQL queries indicative of injection attempts. 4. Employ Web Application Firewalls (WAFs) with SQL injection detection and prevention capabilities tailored to Centreon's traffic patterns. 5. Segregate the Centreon database with least privilege principles to limit the impact of any potential injection. 6. Regularly back up Centreon configurations and databases to enable recovery in case of compromise. 7. Stay alert for official patches or updates from Centreon and apply them promptly once available. 8. Conduct internal penetration testing focusing on SQL injection vectors in Centreon to identify and remediate similar vulnerabilities proactively.
