Summary

CVE-2025-59783 is a high-severity OS Command Injection (CWE-78) vulnerability in 2N Access Commander. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 45% of CVEs by exploit likelihood; 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-2025-59783 is an OS command injection vulnerability (CWE-78) affecting the API endpoint for user synchronization in 2N Access Commander version 3.4.1. The issue arises from insufficient input validation, which allows malicious input to be processed as operating system commands. Published on 2026-03-04, it has a CVSS v3.1 base score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H), indicating high severity with network accessibility and significant impacts on confidentiality, integrity, and availability.

Exploitation requires an attacker to first authenticate with administrator privileges on the affected system. Once authenticated, the attacker can inject and execute arbitrary OS commands remotely with low complexity and no user interaction required, potentially compromising the entire system.

The vendor has published an advisory with mitigation details, including a patch for 2N Access Commander version 3.5, available at https://www.2n.com/en-GB/download/cve_2025_59783_acom_3_5_v1pdf. Security practitioners should apply this update promptly to affected installations.

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 mostly match

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.

PR.PS-02 partial match
prevents

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).
