An exposure of sensitive information to an unauthorized actor vulnerability in FortiOS CLI 7.0.0, 6.4.0 through 6.4.6, 6.2.0 through 6.2.9, 6.0.x and 5.6.x may allow a local and authenticated user assigned to a specific VDOM to retrieve other VDOMs information such as the admin account list and the network interface list.

Security readout for executives and security teams

Plain-English summary

This FortiOS issue lets an authenticated user assigned to one VDOM see limited information from other VDOMs, such as admin account lists and network interface lists. It is a confidentiality problem, not a reported takeover or outage issue. Business urgency depends on whether VDOM separation is used for tenant, customer, or internal security boundaries.

Executive priority

Prioritize remediation where FortiGate VDOMs separate customers, business units, or privileged network zones. This is not rated critical, but it can weaken segmentation assumptions and reveal operational details useful for follow-on intrusion planning.

Technical view

CVE-2021-32600 affects FortiOS CLI in 7.0.0, 6.4.0-6.4.6, 6.2.0-6.2.9, 6.0.x, and 5.6.x. A local authenticated user assigned to a specific VDOM may retrieve information from other VDOMs. CVSS 3.1 is 5.0 with low privileges, no user interaction, changed scope, and low confidentiality impact.

Likely exposure

Exposure is most relevant on FortiOS deployments using VDOMs where users have CLI access scoped to individual VDOMs. Single-VDOM or tightly restricted administrator environments are less exposed, but version inventory is still required.

Exploitation context

The source bundle does not show CISA KEV listing or active exploitation evidence. The vulnerability requires an authenticated user with VDOM assignment and appears limited to information disclosure, based on the provided CVE description and CVSS vector.

Researcher notes

Key limits are authenticated access, VDOM assignment, and confidentiality-only impact in the provided data. The affected surface is FortiOS CLI behavior across multiple major branches. The bundle does not include CWE mapping, exploit details, or explicit fixed versions.

Mitigation direction

  • Check Fortinet advisory FG-IR-20-243 for current fixed-release guidance.
  • Upgrade affected FortiOS systems according to Fortinet guidance.
  • Restrict FortiOS CLI access to trusted administrators only.
  • Review VDOM administrator assignments and remove unnecessary access.
  • Treat exposed admin and interface lists as sensitive operational data.

Validation and detection

  • Inventory FortiOS versions across all FortiGate devices.
  • Identify systems using VDOMs and delegated VDOM administrators.
  • Review which users have CLI access to FortiOS.
  • Compare discovered versions against the affected ranges.
  • Document whether vendor-fixed releases have been applied.
