Summary

CVE-2022-27483 is a high-severity OS Command Injection (CWE-78) vulnerability in Fortinet Fortianalyzer. Its CVSS base score is 7.2 (High).

Operationally, ranked in the top 9.7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

Deeper analysis

CVE-2022-27483 is an OS command injection vulnerability (CWE-78) affecting Fortinet FortiManager versions 7.0.0–7.0.3, 6.4.0–6.4.7, 6.2.x and 6.0.x as well as FortiAnalyzer versions in the same ranges. The flaw resides in the handling of diagnose system CLI commands and permits improper neutralization of special elements, enabling execution of arbitrary operating-system commands.

An attacker with high-privileged network access can supply crafted input to these CLI commands and obtain arbitrary shell code execution with root privileges on the affected appliance. The CVSS 7.2 vector reflects network attack reachability, low attack complexity, and high impact on confidentiality, integrity, and availability without user interaction.

Fortinet’s advisory FG-IR-22-049, referenced at fortiguard.com/psirt/FG-IR-22-049, addresses the issue for the listed product lines. The associated EPSS score has remained flat at 0.0537 with no material increase since disclosure.

Mitigating Controls

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

SC-27 Platform-independent Applications
addresses: CWE-78

Platform-independent apps typically execute inside a managed runtime or sandbox that restricts direct OS command execution, reducing the ability to exploit OS command injection.

SI-10 Information Input Validation
addresses: CWE-78

Validates inputs to block special elements that would alter OS command execution.
