An exposure of sensitive information to an unauthorized actor vulnerability in FortiOS version 6.2.4 and below, version 6.0.10 and belowmay allow remote authenticated actors to read the SSL VPN events log entries of users in other VDOMs by executing "get vpn ssl monitor" from the CLI. The sensitive data includes usernames, user groups, and IP address.

Security readout for executives and security teams

Plain-English summary

This FortiOS issue lets a remote authenticated user see SSL VPN event log details belonging to users in other VDOMs. Exposed data includes usernames, user groups, and IP addresses. It is not described as unauthenticated control or system takeover, but it weakens tenant or segmentation boundaries on affected firewalls.

Executive priority

Treat as a moderate-priority firewall hygiene issue. It does not indicate unauthenticated compromise, but it can expose user and network identity data across VDOM boundaries, which matters for privacy, segmentation, and managed-service environments.

Technical view

CVE-2020-29010 is a CWE-200 information exposure flaw in FortiOS 6.2.4 and below, and 6.0.10 and below. A remote authenticated actor with CLI access may read SSL VPN event log entries for users in other VDOMs. CVSS v3.1 is 4.9, with low confidentiality impact and no integrity or availability impact.

Likely exposure

Exposure is most relevant to organizations running affected FortiOS 6.2.x or 6.0.x releases with SSL VPN, VDOM separation, and authenticated users who can access CLI functions.

Exploitation context

The provided sources do not show CISA KEV listing or active exploitation. Exploitation requires authentication and CLI access, so risk depends heavily on administrative account control, remote management exposure, and VDOM trust boundaries.

Researcher notes

Evidence is limited to the CVE record and Fortinet PSIRT reference in the bundle. No exploit availability, active exploitation, or exact fixed version is provided here, so remediation should be confirmed directly against Fortinet advisory FG-IR-20-103.

Mitigation direction

  • Check Fortinet PSIRT guidance for the fixed or recommended FortiOS release.
  • Upgrade affected FortiOS systems according to vendor guidance.
  • Restrict CLI access to trusted administrators only.
  • Review accounts with remote management or VDOM administration privileges.
  • Limit management-plane exposure to approved networks.

Validation and detection

  • Inventory FortiOS versions against 6.2.4 and below, and 6.0.10 and below.
  • Confirm whether SSL VPN and VDOMs are in use on affected appliances.
  • Review which authenticated users have CLI access.
  • Check administrative logs for unusual SSL VPN log viewing activity.
  • Document compensating controls if immediate upgrade is not possible.
