Summary

CVE-2025-24383 is a critical-severity OS Command Injection (CWE-78) vulnerability in Dell Unity Operating Environment. Its CVSS base score is 9.1 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 36% 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.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

Dell Unity versions 5.4 and prior contain an OS command injection vulnerability tracked as CVE-2025-24383 and CWE-78. The flaw carries a CVSS 3.1 score of 9.1 and permits improper neutralization of special elements in operating-system commands, enabling manipulation of file-system operations with root privileges.

An unauthenticated attacker with remote network access can exploit the issue to delete arbitrary files on the affected storage system, including critical system files that could lead to denial of service or further compromise.

Dell security advisory DSA-2025-116 addresses the vulnerability and explicitly recommends that customers upgrade Dell Unity, UnityVSA, and Unity XT systems at the earliest opportunity.

The associated EPSS score rose from a low baseline to a peak of 0.1182 on 2026-02-03 before receding to its current value of 0.0246, indicating a period of increased exploitation interest after public disclosure.

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).
