CVE-2025-56109 is an OS Command Injection vulnerability (CWE-78) in the Ruijie RG-BCR RG-BCR860 device. The flaw exists in the action_wireless function of the file /usr/lib/lua/luci/control/admin/wireless.lua, enabling attackers to execute arbitrary operating system 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).
The vulnerability can be exploited by attackers with low privileges, such as authenticated users with minimal access rights on the affected device. Exploitation occurs remotely over the network with low complexity and no user interaction required. Successful attacks allow arbitrary command execution, resulting in high impacts to confidentiality, integrity, and availability, potentially leading to full device compromise.

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.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
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).
