Security readout for executives and security teams
Plain-English summary
CVE-2021-37557 is a SQL injection issue in Centreon's graph image generation feature. An authenticated user with low privileges could send malicious input through the image-generation index parameter and cause arbitrary SQL commands to run. This matters where Centreon accounts are broadly issued or exposed beyond a tightly controlled operations team.
Executive priority
Treat this as a high-priority remediation for internet-accessible or widely accessible Centreon systems. The issue requires authentication, but low privilege is enough, so compromised or excess user accounts may create material database risk.
Technical view
Centreon versions before 20.04.14, 20.10.8, and 21.04.2 are reported vulnerable in include/views/graphs/generateGraphs/generateImage.php. The vulnerable input is the index parameter. The public record describes remote authenticated, low-privileged SQL injection leading to arbitrary SQL command execution. No CVSS vector or CWE is provided in the supplied bundle.
Likely exposure
Exposure is likely limited to organizations running Centreon versions earlier than 20.04.14, 20.10.8, or 21.04.2, especially where non-admin users can authenticate to Centreon. The supplied data does not identify other affected products.
Exploitation context
The supplied sources state remote authenticated exploitation by low-privileged users is possible. CISA KEV status is false in the bundle, and no cited source here confirms active exploitation in the wild.
Researcher notes
The strongest public facts are the vulnerable endpoint, affected version ranges, low-privileged authenticated prerequisite, and arbitrary SQL impact. The bundle lacks CVSS, CWE, detailed exploit status, and complete remediation notes beyond fixed-version inference.
Mitigation direction
- Upgrade Centreon to 20.04.14, 20.10.8, 21.04.2, or later.
- Restrict Centreon access to authorized operational users only.
- Review low-privileged Centreon accounts for unnecessary access.
- Check vendor guidance and the referenced pull request for fix details.
- Monitor requests involving generateImage.php and the index parameter.
Validation and detection
- Inventory Centreon deployments and record exact versions.
- Flag versions earlier than 20.04.14, 20.10.8, or 21.04.2.
- Confirm whether low-privileged users can authenticate to Centreon.
- Review application logs for unusual generateImage.php index activity.
- Verify remediation by confirming the upgraded Centreon version.
