Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly counters CWE-78 OS command injection by requiring validation and neutralization of special elements in inputs to OS commands.

SI-2 Flaw Remediation good match

prevent

Remediates the specific CVE-2025-55055 flaw through timely installation of vendor-provided patches addressing the improper neutralization.

AC-6 Least Privilege partial match

prevent

Reduces the attack surface and potential impact of exploitation by enforcing least privilege, given the PR:H requirement.

NVD Description

CWE-78 Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

Deeper analysisAI

CVE-2025-55055, published on 2025-11-17T18:15:57.033, is classified as CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'). It carries a CVSS v3.1 base score of 6.8 (AV:N/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:H). The specific software or component affected is not identified in the provided details.

The vulnerability can be exploited over the network with low attack complexity by an attacker possessing high privileges (PR:H), requiring user interaction (UI:R) to succeed. Successful exploitation enables high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H) without changing scope.
