A SQL injection vulnerability in a MediaWiki script in Centreon before 20.04.14, 20.10.8, and 21.04.2 allows remote unauthenticated attackers to execute arbitrary SQL commands via the host_name and service_description parameters. The vulnerability can be exploited only when a valid Knowledge Base URL is configured on the Knowledge Base configuration page and points to a MediaWiki instance. This relates to the proxy feature in class/centreon-knowledge/ProceduresProxy.class.php and include/configuration/configKnowledge/proxy/proxy.php.

Security readout for executives and security teams

Plain-English summary

CVE-2021-37558 is a SQL injection flaw in Centreon’s Knowledge Base proxy integration. An unauthenticated remote attacker could run arbitrary SQL only when Centreon is configured with a valid Knowledge Base URL pointing to MediaWiki. The issue is fixed in Centreon 20.04.14, 20.10.8, and 21.04.2.

Executive priority

Prioritize remediation for internet-reachable or broadly accessible Centreon instances using the MediaWiki Knowledge Base integration. The business risk is higher because Centreon commonly monitors critical infrastructure, but the documented exploitability depends on a specific configuration.

Technical view

The flaw affects Centreon before 20.04.14, 20.10.8, and 21.04.2. The vulnerable path relates to class/centreon-knowledge/ProceduresProxy.class.php and include/configuration/configKnowledge/proxy/proxy.php. The host_name and service_description parameters are identified as SQL injection inputs, conditional on the MediaWiki Knowledge Base proxy feature being configured.

Likely exposure

Exposure is limited to affected Centreon versions where the Knowledge Base configuration contains a valid URL pointing to a MediaWiki instance. Centreon deployments without this configured integration are not described as exploitable by the provided sources.

Exploitation context

The provided CVE record says the issue is remotely exploitable without authentication under the stated configuration condition. CISA KEV status is false in the bundle, and no provided source claims active exploitation.

Researcher notes

The source bundle lacks CVSS, CWE, and detailed affected CPE data. Analysis should stay tied to the Centreon versions and configuration condition stated in the CVE. The GitHub pull request and Synacktiv advisory are the key technical references for validating the fix path.

Mitigation direction

  • Upgrade Centreon to 20.04.14, 20.10.8, 21.04.2, or later applicable versions.
  • Check Centreon vendor guidance for any branch-specific remediation details.
  • Disable or remove the MediaWiki Knowledge Base URL if the integration is not required.
  • Restrict external access to the Centreon web interface where operationally feasible.

Validation and detection

  • Inventory Centreon versions and compare them with the fixed release thresholds.
  • Review Knowledge Base configuration for a valid URL pointing to MediaWiki.
  • Confirm whether the Knowledge Base proxy feature is reachable by unauthenticated users.
  • Review web and application logs for suspicious Knowledge Base proxy activity.
