A improper neutralization of special elements used in an os command ('os command injection') in Fortinet FortiManager version 7.0.0 through 7.0.3, 6.4.0 through 6.4.7, 6.2.x and 6.0.x and FortiAnalyzer version 7.0.0 through 7.0.3, version 6.4.0 through 6.4.7, 6.2.x and 6.0.x allows attacker to execute arbitrary shell code as `root` user via `diagnose system` CLI commands.

Security readout for executives and security teams

Plain-English summary

FortiManager and FortiAnalyzer versions listed by the CVE can let a highly privileged attacker run operating-system commands as root through diagnose system CLI commands. This is serious for organizations relying on these platforms to manage or analyze Fortinet deployments, but the provided sources require high privileges and do not show known active exploitation.

Executive priority

Treat as high priority if affected appliances support production security operations or centralized device management. The issue requires high privileges, lowering broad attacker reach, but successful exploitation gives root control over sensitive infrastructure.

Technical view

The flaw is OS command injection from improper neutralization in diagnose system CLI command handling. It affects FortiManager and FortiAnalyzer 7.0.0-7.0.3, 6.4.0-6.4.7, 6.2.x, and 6.0.x. CVSS 3.1 is 7.2 with network access, low complexity, high privileges required, and root-level confidentiality, integrity, and availability impact.

Likely exposure

Exposure is most likely where vulnerable FortiManager or FortiAnalyzer instances are reachable by administrators or automation accounts with high privileges. The public source bundle does not establish unauthenticated exposure or compromise without privileged CLI access.

Exploitation context

The source bundle describes arbitrary shell code execution as root via diagnose system CLI commands. CISA KEV status is false in the bundle, and no cited source states active exploitation. Exploitability still matters because successful abuse compromises a central management or analytics appliance.

Researcher notes

Evidence supports root command execution through privileged CLI command injection, not public unauthenticated remote code execution. The bundle does not provide exploit details, fixed versions, or active exploitation evidence beyond the Fortinet advisory and CVE metadata.

Mitigation direction

  • Inventory FortiManager and FortiAnalyzer versions against the affected version list.
  • Review Fortinet PSIRT FG-IR-22-049 for vendor-supported fixed releases or mitigations.
  • Restrict administrative and CLI access to trusted operators and management networks.
  • Remove unnecessary high-privilege accounts and review automation credentials.
  • Prioritize upgrade or vendor mitigation for internet-reachable management paths.

Validation and detection

  • Confirm deployed FortiManager and FortiAnalyzer versions, including standby or lab appliances.
  • Review administrator accounts with access to diagnose system CLI commands.
  • Check logs for unusual privileged CLI activity on affected appliances.
  • Verify management interfaces are not broadly reachable.
  • Document remediation status against the Fortinet PSIRT advisory.
