Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

Directly addresses improper neutralization of special elements in OS commands by requiring validation and sanitization of user inputs to prevent command injection.

prevent

Requires timely remediation of the specific OS command injection flaw through vendor patching as detailed in Dell's security advisory.

prevent

Enforces least privilege to limit the scope and impact of privilege escalation resulting from successful command injection by low-privileged local attackers.

MITRE ATT&CK Enterprise TechniquesAI

T1059.004 Unix Shell Execution
Adversaries may abuse Unix shell commands and scripts for execution.
T1068 Exploitation for Privilege Escalation Privilege Escalation
Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
Why these techniques?

OS command injection enables arbitrary command execution via Unix shell (T1059.004) and is exploited for privilege escalation (T1068) from local low-privileged access.

Deeper analysisAI

CVE-2025-24386 is an Improper Neutralization of Special Elements used in an OS Command, classified as an OS Command Injection vulnerability (CWE-78), affecting Dell Unity storage systems in versions 5.4 and prior. This flaw allows malicious input to alter the intended behavior of OS commands executed by the system.

A low-privileged attacker with local access can exploit this vulnerability to achieve arbitrary command execution and privilege escalation. The CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) reflects high impacts on confidentiality, integrity, and availability in a local attack scenario with low complexity and no user interaction required.

Dell has issued security advisory DSA-2025-116, detailing a security update for Dell Unity, Dell UnityVSA, and Dell Unity XT to remediate multiple vulnerabilities, including CVE-2025-24386. Security practitioners should consult the advisory at https://www.dell.com/support/kbdoc/en-us/000300090/dsa-2025-116-security-update-for-dell-unity-dell-unityvsa-and-dell-unity-xt-security-update-for-multiple-vulnerabilities and apply the recommended patches promptly.
