Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

Requires input validation mechanisms at the pwdmodify endpoint to reject crafted POST requests containing OS command injection payloads.

prevent

Mandates timely remediation of the command injection flaw in /usr/lib/lua/luci/modules/common.lua through patching or updates.

prevent

Enforces restrictions on POST request inputs to the pwdmodify function, such as character sets and lengths, to block injection attempts.

MITRE ATT&CK Enterprise TechniquesAI

T1059.004 Unix Shell Execution
Adversaries may abuse Unix shell commands and scripts for execution.
T1068 Exploitation for Privilege Escalation Privilege Escalation
Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
Why these techniques?

OS command injection directly enables arbitrary Unix shell command execution (T1059.004) on the network device and facilitates privilege escalation from low-privileged access (PR:L) to full system compromise (T1068).

NVD 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 pwdmodify in file /usr/lib/lua/luci/modules/common.lua.

Deeper analysisAI

CVE-2025-56108 is an OS command injection vulnerability (CWE-78) affecting the Ruijie X30-PRO device, specifically version X30-PRO-V1_09241521. The flaw resides in the pwdmodify function within the file /usr/lib/lua/luci/modules/common.lua, where attackers can execute arbitrary operating system commands by sending a crafted POST request. The vulnerability 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), indicating high severity due to its network accessibility, low attack complexity, and potential for high impact on confidentiality, integrity, and availability.

An attacker with low privileges (PR:L), such as an authenticated user on the device, can exploit this vulnerability remotely over the network without user interaction. By crafting a malicious POST request to the pwdmodify endpoint, the attacker injects and executes arbitrary OS commands, potentially leading to full system compromise, including data exfiltration, persistence, or further lateral movement within the network.
