Security readout for executives and security teams
Plain-English summary
This flaw lets a highly privileged user abuse Pimcore Customer Data Framework to read or change database information through blind SQL injection. It is not described as remotely exploitable by anonymous users, but it can affect sensitive customer data if privileged access is compromised or misused.
Executive priority
Treat as a scheduled but important remediation for affected customer-data systems. Prioritize faster if privileged accounts are broadly shared, exposed through VPN weaknesses, or connected to high-value customer datasets.
Technical view
CVE-2021-31867 is CWE-89 Boolean-based blind SQL injection in the $id parameter of SegmentAssignmentController.php in Pimcore Customer Data Framework 3.0.0 and earlier. CVSS 3.1 is 6.5: network reachable, low complexity, high privileges required, no user interaction, high confidentiality and integrity impact.
Likely exposure
Exposure is likely limited to organizations running Pimcore Customer Data Framework 3.0.0 or earlier, especially where privileged application access exists outside tightly controlled administrative networks.
Exploitation context
The provided sources do not report active exploitation, and the CVE is not marked KEV. The privilege requirement lowers broad internet risk, but successful abuse could still expose or alter important customer data.
Researcher notes
Evidence identifies the vulnerable component, parameter, weakness class, CVSS vector, and fixed version. The bundle does not include exploit telemetry, detailed patch diff, or deployment-specific attack paths, so validation should stay version- and exposure-focused.
Mitigation direction
- Upgrade Pimcore Customer Data Framework to version 3.0.2 or later.
- Identify and retire any 3.0.0 or earlier installations.
- Restrict privileged Pimcore access to trusted users and networks.
- Review vendor guidance before applying compensating controls.
Validation and detection
- Inventory Pimcore Customer Data Framework versions across production and staging.
- Confirm SegmentAssignmentController.php is from a fixed release.
- Review privileged account access paths for unnecessary exposure.
- Check application and database logs for unusual privileged data access.
