A privilege chaining vulnerability [CWE-268] in FortiManager and FortiAnalyzer 6.0.x, 6.2.x, 6.4.0 through 6.4.7, 7.0.0 through 7.0.3 may allow a local and authenticated attacker with a restricted shell to escalate their privileges to root due to incorrect permissions of some folders and executable files on the system.

Security readout for executives and security teams

Plain-English summary

Fortinet FortiManager and FortiAnalyzer versions listed in the advisory contain a local privilege escalation issue. An authenticated user already limited to a restricted shell could potentially gain root-level control because some folders and executables have incorrect permissions.

Executive priority

Treat as a planned but important remediation for Fortinet management infrastructure. The flaw is not described as remotely exploitable without credentials, but root escalation on management appliances can materially affect network security operations.

Technical view

CVE-2022-26118 is a CWE-268 privilege chaining flaw affecting FortiManager and FortiAnalyzer 6.0.x, 6.2.x, 6.4.0-6.4.7, and 7.0.0-7.0.3. CVSS 3.1 is 6.7 with local access, low complexity, high privileges required, no user interaction, and high confidentiality, integrity, and availability impact.

Likely exposure

Exposure is limited to organizations running the affected FortiManager or FortiAnalyzer versions where users or processes can authenticate locally into a restricted shell. Internet-only unauthenticated exposure is not supported by the provided evidence.

Exploitation context

The CVE is not listed as CISA KEV in the provided bundle. The CVSS vector indicates exploitation requires local access and high privileges, but successful exploitation could result in root privileges.

Researcher notes

Evidence supports local authenticated privilege escalation through incorrect permissions, not remote initial access. The supplied bundle does not include exploit details or explicit fixed release numbers, so remediation should be tied to Fortinet’s advisory rather than inferred.

Mitigation direction

  • Identify FortiManager and FortiAnalyzer instances and record exact versions.
  • Check Fortinet advisory FG-IR-21-056 for vendor-approved fixed versions or workarounds.
  • Upgrade affected systems according to Fortinet guidance.
  • Restrict local and restricted-shell access to only necessary trusted administrators.
  • Review privileged account hygiene on management appliances.

Validation and detection

  • Compare appliance versions against the affected version ranges in the CVE record.
  • Confirm no affected FortiManager or FortiAnalyzer version remains in production.
  • Review local accounts with restricted-shell access for necessity and ownership.
  • After remediation, verify vendor guidance reports the system as no longer affected.
  • Check operational logs for unusual local privilege or shell activity.
