CVE-2025-4646 is a high-severity vulnerability classified under CWE-269 (Improper Privilege Management) affecting Centreon web versions from 24.04.0 before 24.04.10 and from 24.10.0 before 24.10.4. Centreon web is a widely used IT infrastructure monitoring solution that provides real-time monitoring and alerting capabilities. The vulnerability specifically resides in the API Token creation form modules, where improper privilege management allows an attacker with some level of authenticated access (privilege level: high) to escalate their privileges further. The CVSS 3.1 score of 7.2 indicates a high impact with network attack vector (AV:N), low attack complexity (AC:L), requiring high privileges (PR:H), no user interaction (UI:N), and impacting confidentiality, integrity, and availability (C:H/I:H/A:H). This means that an attacker who already has elevated privileges but not full administrative rights can exploit this flaw remotely without user interaction to gain full control or administrative privileges over the Centreon web application. The vulnerability could allow unauthorized access to sensitive monitoring data, modification of monitoring configurations, or disruption of monitoring services, which are critical for maintaining IT infrastructure health and security. Although no known exploits are currently reported in the wild, the presence of this vulnerability in a critical monitoring tool makes it a significant risk if left unpatched.

For European organizations, the impact of this vulnerability is substantial. Centreon is commonly deployed in enterprise environments, including government, telecommunications, finance, and critical infrastructure sectors across Europe. Exploitation could lead to unauthorized privilege escalation within monitoring systems, allowing attackers to manipulate monitoring data, disable alerts, or conceal malicious activities, thereby undermining incident detection and response capabilities. This could result in prolonged undetected breaches, data exfiltration, or operational disruptions. In sectors with strict regulatory requirements such as GDPR, unauthorized access or tampering with monitoring data could also lead to compliance violations and financial penalties. The high confidentiality, integrity, and availability impact means that organizations relying on Centreon for infrastructure monitoring could face significant operational and reputational damage if this vulnerability is exploited.

To mitigate this vulnerability, European organizations should prioritize upgrading Centreon web installations to versions 24.04.10 or later and 24.10.4 or later, where the issue is resolved. Since no patch links are provided, organizations should monitor Centreon's official channels for the release of security patches or updates addressing CVE-2025-4646. In the interim, organizations should restrict access to the Centreon web interface and API token creation modules to only trusted administrators using network segmentation and strong access controls. Implement multi-factor authentication (MFA) for all privileged accounts to reduce the risk of compromised credentials being exploited. Regularly audit user privileges and API tokens to detect and revoke any unauthorized or suspicious access. Additionally, monitor Centreon logs for unusual activity related to API token creation or privilege changes. Employ network-level protections such as web application firewalls (WAFs) to detect and block anomalous requests targeting the API token creation endpoints. Finally, integrate Centreon monitoring with Security Information and Event Management (SIEM) systems to enhance detection of potential exploitation attempts.
