Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-56095 is an OS Command Injection vulnerability (CWE-78) in the Ruijie RG-EW1200G PRO device across firmware versions V1.00, V2.00, V3.00, and V4.00. The issue affects the module_set function in the file /usr/local/lua/dev_sta/nbr_cwmp.lua, where attackers can execute arbitrary commands through a crafted POST request. Published on 2025-12-11, it carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), reflecting high severity due to network accessibility, low complexity, and significant impacts on confidentiality, integrity, and availability.
Remote attackers with low privileges can exploit this vulnerability by sending a specially crafted POST request to the vulnerable endpoint. No user interaction is required, enabling straightforward exploitation over the network. Successful attacks allow arbitrary OS command execution on the device, potentially leading to full remote code execution, data compromise, system modification, or denial of service.

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).
