Security readout for executives and security teams
Plain-English summary
CVE-2020-9287 affects the FortiClient EMS online installer version 6.2.1 and below. If an attacker can control the folder where the installer is located, the installer may load attacker-supplied DLL files and run arbitrary code. This is primarily a workstation or software-staging risk, not a remotely exploitable network service issue.
Executive priority
Treat as a controlled remediation item. Prioritize environments where endpoint software installers are staged on shared drives or run by administrators from writable folders.
Technical view
The issue is an unsafe search path in FortiClientEMSOnlineInstaller.exe. A local attacker with control over the installer’s directory could influence DLL loading, including Filter Library DLL files, leading to arbitrary code execution in the installer’s execution context.
Likely exposure
Exposure is most likely where old FortiClient EMS online installers are stored in user-writable download folders, shared software repositories, or deployment staging paths.
Exploitation context
The bundle does not show KEV listing or active exploitation evidence. Exploitation requires local control of the installer directory and execution of the affected installer.
Researcher notes
Evidence is limited to the CVE description and Fortinet advisory reference. No CVSS, CWE, confirmed fixed version, or exploitation details are present in the supplied bundle.
Mitigation direction
- Check Fortinet advisory FG-IR-19-060 for vendor-approved remediation.
- Replace affected FortiClient EMS online installers with current vendor-provided installers.
- Remove old FortiClientEMSOnlineInstaller.exe copies from shared or user-writable locations.
- Restrict write access to software staging and deployment directories.
- Run installers only from trusted, access-controlled paths.
Validation and detection
- Inventory FortiClient EMS online installer copies and versions.
- Identify any FortiClientEMSOnlineInstaller.exe version 6.2.1 or below.
- Review ACLs on folders containing the installer.
- Check deployment records for installer execution from writable locations.
- Confirm remediation against Fortinet FG-IR-19-060 guidance.
