Security readout for executives and security teams
Plain-English summary
CVE-2021-23230 is a critical SQL injection issue in Gallagher Command Centre's OPCUA interface. A remote, low-privileged Command Centre Operator could modify Command Centre databases without detection, creating serious integrity and operational risk for affected installations.
Executive priority
Treat as urgent for affected sites because it can undermine database integrity in a physical security management platform. Prioritize inventory, vendor-guided upgrades, and access restriction, especially where OPCUA access is broadly reachable.
Technical view
The flaw is CWE-89 SQL injection in the OPCUA interface. Affected versions include 8.40 before 8.40.1888 MR3, 8.30 before 8.30.1359 MR3, 8.20 before 8.20.1259 MR5, 8.10 before 8.10.1284 MR7, and 8.00 or earlier.
Likely exposure
Exposure is limited to organizations running affected Gallagher Command Centre versions with the OPCUA interface reachable by Command Centre Operator users. The sources do not state internet exposure requirements or broader product impact.
Exploitation context
The supplied data shows no CISA KEV listing and provides no evidence of active exploitation. The CVSS vector indicates remote network exploitation, low complexity, low privileges, no user interaction, changed scope, and high confidentiality, integrity, and availability impact.
Researcher notes
Evidence is concise and vendor-centered. The sources identify SQL injection and affected version thresholds, but do not provide exploit details, indicators of compromise, or a standalone mitigation beyond moving outside affected versions and following vendor guidance.
Mitigation direction
- Identify all Gallagher Command Centre deployments and versions.
- Review Gallagher's advisory for supported remediation guidance.
- Upgrade affected branches to non-affected maintenance releases at or above the listed fixed versions.
- Restrict OPCUA interface access to trusted, necessary users and networks.
- Review Command Centre database integrity and operator activity logs where available.
Validation and detection
- Confirm whether Gallagher Command Centre is deployed.
- Check installed version against the affected version ranges.
- Determine whether the OPCUA interface is enabled and reachable.
- Review Command Centre Operator accounts with access to the interface.
- Verify remediation by confirming version is outside the affected ranges.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
