Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify FortiClient installationCheck for FortiClient installation on Windows by reviewing the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Fortinet\FortiClient or looking in C:\Program Files\Fortinet\FortiClient for the application directoryAffected if FortiClient is installed on the system
-
Determine installed FortiClient versionRead the version information from the FortiClient executable (e.g., FortiClient.exe) by right-clicking the file in the installation directory, selecting Properties, and reviewing the Details tab, or query the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Fortinet\FortiClient for the Version valueAffected if The displayed version is 6.0.4 or any earlier version (e.g., 6.0.3, 6.0.2, 6.0.1, 6.0.0, 5.x versions)
-
Confirm application is in useCheck if FortiClient processes are running (e.g., FortiClient.exe, FortiTray.exe, or FortiSSLVPNdaemon.exe) using Task Manager or by running 'tasklist | findstr -i forti' in Command PromptAffected if FortiClient is actively running on the system and an unprivileged local user can interact with the application interface
You are affected if FortiClient for Windows is installed with version 6.0.4 or earlier, as this version range contains the command injection vulnerability that allows local privilege escalation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade FortiClient for Windows to version 6.0.5 or later to address the command injection vulnerability. In enterprise environments, test the upgrade thoroughly in a staging environment before broad deployment to ensure compatibility with existing security infrastructure.
