Summary
CVE-2023-37937 is a high-severity OS Command Injection (CWE-78) vulnerability in Fortinet Fortiswitch. Its CVSS base score is 7.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique NTDS (T1003.003); ranked at the 43th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2023-37937 is an OS command injection vulnerability (CWE-78) affecting Fortinet FortiSwitch versions 7.4.0, 7.2.0 through 7.2.5, 7.0.0 through 7.0.7, 6.4.0 through 6.4.13, 6.2.0 through 6.2.7, and 6.0.0 through 6.0.7. The issue arises from improper neutralization of special elements used in OS commands, enabling attackers to execute unauthorized code or commands via the FortiSwitch CLI. It carries a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) and was published on 2025-01-14.
The vulnerability can be exploited by an attacker with local access to the FortiSwitch and low privileges. Such an attacker can use the CLI to inject and execute arbitrary OS commands, potentially leading to high impacts on confidentiality, integrity, and availability, such as unauthorized data access, modification, or denial of service.
Mitigation details, including patches, are outlined in the Fortinet PSIRT advisory at https://fortiguard.com/psirt/FG-IR-23-258.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover missing or incorrect command sanitization during development.
Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.
Least privilege reduces the permissions available to any process that could be subverted by injected commands.
Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.
Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.
Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
