Security readout for executives and security teams
Plain-English summary
This affects Fortinet FortiClientWindows 6.0.2 and earlier. A flaw in the Windows NDIS miniport driver can let an attacker cause a denial of service. The public bundle does not provide CVSS severity, prerequisites, or confirmed fix details.
Executive priority
Treat this as a legacy endpoint availability risk. It is not confirmed as actively exploited in the supplied sources, but affected FortiClientWindows versions should be identified and remediated through normal vulnerability management.
Technical view
CVE-2018-9190 is a null pointer dereference in FortiClientWindows 6.0.2 and earlier, reachable via the NDIS miniport driver, resulting in denial of service. The provided sources do not define CVSS, CWE, privileges, attack vector, or detailed remediation.
Likely exposure
Exposure is limited to Windows endpoints running Fortinet FortiClientWindows 6.0.2 or earlier. Organizations with legacy FortiClient deployments should verify versions through endpoint inventory and security tooling.
Exploitation context
The supplied data does not show CISA KEV listing, active exploitation, or public exploit details. It only states an attacker can cause denial of service via the NDIS miniport driver.
Researcher notes
Evidence is sparse: no CVSS, CWE, exploit status, or attack prerequisites are provided. Analysis should stay constrained to denial of service in FortiClientWindows 6.0.2 and earlier via the NDIS miniport driver.
Mitigation direction
- Review Fortinet advisory FG-IR-18-092 for fixed versions or workarounds.
- Inventory Windows endpoints for FortiClientWindows 6.0.2 and earlier.
- Prioritize remediation on endpoints supporting critical users or operational workflows.
- Move affected clients to vendor-supported versions according to Fortinet guidance.
Validation and detection
- Query endpoint inventory for installed FortiClientWindows versions.
- Confirm whether FortiClientWindows 6.0.2 or earlier remains deployed.
- Document affected asset owners and operational criticality.
- Verify remediation state against Fortinet advisory guidance.
