Description

OS Command Injection vulnerability in Ruijie X30-PRO X30-PRO-V1_09241521 allowing attackers to execute arbitrary commands via a crafted POST request to the module_get in file /usr/local/lua/dev_sta/host_access_delay.lua.

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match
prevent

Directly validates and sanitizes crafted POST request inputs to the module_get function, preventing OS command injection exploitation.

SI-2 Flaw Remediation good match
prevent

Mandates timely flaw remediation, such as applying vendor patches for the vulnerability in /usr/local/lua/dev_sta/host_access_delay.lua.

AC-6 Least Privilege partial match
prevent

Limits privileges of low-privileged users and the handling process, reducing impact of arbitrary OS command execution.

Security SummaryAI

CVE-2025-56094 is an OS Command Injection vulnerability (CWE-78) in the Ruijie X30-PRO device, specifically version X30-PRO-V1_09241521. The issue affects the module_get function in the file /usr/local/lua/dev_sta/host_access_delay.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).

Attackers with low privileges, such as standard authenticated users, can exploit this vulnerability remotely over the network with low complexity and no user interaction required. Successful exploitation allows arbitrary command execution on the underlying OS, resulting in high impacts to confidentiality, integrity, and availability, potentially leading to full device compromise.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
attack.mitre.org →
T1059.004 Unix Shell Execution
Adversaries may abuse Unix shell commands and scripts for execution.
attack.mitre.org →
T1068 Exploitation for Privilege Escalation Privilege Escalation
Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
attack.mitre.org →
Why these techniques?

OS command injection via crafted POST to web interface on network device directly enables exploitation of public-facing application (T1190), arbitrary Unix shell command execution (T1059.004), and privilege escalation from low privileges to arbitrary OS commands (T1068).
