Security readout for executives and security teams
Plain-English summary
GeoServer DB2 DataStore Extension before 2.27.0 allows an administrator to use a malicious DB2 JDBC URL in a store connection, potentially leading to remote code execution. The required admin privilege lowers likelihood, but impact is severe if an admin account is compromised or misused.
Executive priority
Treat as high priority where GeoServer uses DB2 support. Admin privileges are required, but successful exploitation can compromise the server, so patch affected environments and review privileged access promptly.
Technical view
CVE-2025-27511 affects org.geoserver.extension:gs-db2 versions before 2.27.0. The flaw is described as a JNDI attack path through specially crafted DB2 JDBC URLs in Store Connection handling. The CVSS v3.1 score is 7.2 with high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is limited to GeoServer deployments using the DB2 DataStore Extension below version 2.27.0. The attacker must have administrator privileges according to the source bundle, so prioritize internet-facing or broadly administered GeoServer instances.
Exploitation context
The bundle does not show CISA KEV listing or cited evidence of active exploitation. The attack requires administrator privileges but can result in RCE, making compromised admin credentials or malicious insiders the main practical concern.
Researcher notes
The sources identify CWE-502 and CWE-74, plus a related GeoTools issue reference. Evidence provided does not include exploit availability, active exploitation, or detailed reproduction steps. Keep analysis bounded to affected gs-db2 versions before 2.27.0.
Mitigation direction
- Upgrade GeoServer DB2 DataStore Extension to version 2.27.0 or later.
- Check GeoServer vendor advisory and release notes for deployment-specific guidance.
- Restrict GeoServer administrator access to trusted users and management networks.
- Review administrator accounts and remove stale or unnecessary privileged access.
Validation and detection
- Inventory GeoServer instances and identify whether the DB2 DataStore Extension is installed.
- Confirm installed gs-db2 versions are 2.27.0 or later.
- Review recent administrative changes to DB2 store connection settings.
- Check GeoServer logs for unexpected administrator activity around datastore configuration.
