CVE-2025-56099 is an OS Command Injection vulnerability (CWE-78) in Ruijie RG-YST AP_3.0(1)B11P280YST250F. The issue affects the pwdmodify function in the file /usr/lib/lua/luci/modules/common.lua, where a crafted POST request enables attackers to execute arbitrary operating system commands. The vulnerability was published on 2025-12-11T19:15:55.860 and 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).
An attacker with low privileges (PR:L) can exploit this vulnerability remotely over the network (AV:N) with low attack complexity (AC:L) and no user interaction required (UI:N). By sending a specially crafted POST request to the pwdmodify endpoint, the attacker achieves arbitrary command execution on the underlying OS, resulting in high impacts to confidentiality, integrity, and availability (C:H/I:H/A:H) within the affected system's scope (S:U).

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).
