Security readout for executives and security teams
Plain-English summary
Centreon monitoring installations before 20.04.14, 20.10.8, and 21.04.2 contain an authenticated SQL injection in reporting export. A low-privileged logged-in user could run arbitrary database commands through affected export parameters. This is most urgent where Centreon is reachable by many internal users or exposed beyond tightly controlled administration networks.
Executive priority
Prioritize remediation for shared or externally reachable Centreon environments. The issue lets an authenticated low-privileged user affect the database, which can undermine monitoring integrity and expose operational data.
Technical view
The flaw is in include/reporting/dashboard/csvExport/csv_HostGroupLogs.php. The start and end parameters in reporting CSV export are described as allowing remote authenticated, low-privileged attackers to execute arbitrary SQL commands. The supplied sources do not provide CVSS, CWE, affected CPEs, or detailed exploit-status evidence.
Likely exposure
Exposure is limited to Centreon deployments older than 20.04.14, 20.10.8, or 21.04.2 where authenticated low-privileged users can access reporting export. Internet exposure is not stated in the sources, so assess actual access paths locally.
Exploitation context
The CVE record describes remote authenticated exploitation by a low-privileged user. The source bundle does not show CISA KEV listing or other evidence of active exploitation. Treat exploit maturity as unconfirmed from the provided evidence.
Researcher notes
Focus validation on version checks, reachable export routes, and privilege boundaries for reporting export. Do not assume unauthenticated exposure; the supplied description requires authentication. Evidence is incomplete for CVSS, exploit prevalence, and exact database impact.
Mitigation direction
- Upgrade Centreon to 20.04.14, 20.10.8, 21.04.2, or later vendor-supported versions.
- Check Centreon vendor guidance and the linked fix before applying environment-specific controls.
- Limit Centreon access to trusted users and administrative networks while remediation is pending.
- Review low-privileged accounts with access to reporting export functionality.
Validation and detection
- Inventory Centreon instances and record exact version numbers.
- Confirm no instance is below 20.04.14, 20.10.8, or 21.04.2.
- Verify whether low-privileged users can reach reporting CSV export.
- Review database and application logs for unusual reporting export activity.
