Summary

CVE-2025-67089 is a high-severity Command Injection (CWE-77) vulnerability in Gl-Inet Gl-Axt1800 Firmware. Its CVSS base score is 8.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation of Remote Services (T1210); ranked in the top 41.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploitation of Remote Services (T1210) and 2 other techniques. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Requires validation and sanitization of user-supplied package names in the plugins.install_package RPC method to directly prevent command injection.

SI-2 Flaw Remediation good match

prevent

Mandates timely identification, reporting, and correction of the input sanitization flaw in the router firmware to remediate the vulnerability.

AC-6 Least Privilege partial match

prevent

Enforces least privilege on processes handling RPC calls, limiting the scope and impact of arbitrary root command execution if injection occurs.

MITRE ATT&CK Enterprise TechniquesAI

T1210 Exploitation of Remote Services Lateral Movement

Adversaries may exploit remote services to gain unauthorized access to internal systems once inside of a network.

T1068 Exploitation for Privilege Escalation Privilege Escalation

Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.

attack.mitre.org →

T1059.004 Unix Shell Execution

Adversaries may abuse Unix shell commands and scripts for execution.

attack.mitre.org →

Why these techniques?

Command injection in remote RPC method (plugins.install_package) enables exploitation of remote service (T1210) for arbitrary root command execution (T1059.004 Unix Shell) and privilege escalation from low privileges to root (T1068).

NVD Description

A command injection vulnerability exists in the GL-iNet GL-AXT1800 router firmware v4.6.8. The vulnerability is present in the `plugins.install_package` RPC method, which fails to properly sanitize user input in package names. Authenticated attackers can exploit this to execute arbitrary commands…

Deeper analysisAI

CVE-2025-67089, published on 2026-01-08, is a command injection vulnerability (CWE-77) affecting the GL-iNet GL-AXT1800 router firmware version v4.6.8. The flaw exists in the `plugins.install_package` RPC method, which fails to properly sanitize user input in package names, enabling the injection of malicious commands.

Authenticated attackers with low privileges (PR:L) can exploit this vulnerability over the network (AV:N) with low attack complexity (AC:L) and no user interaction (UI:N). Exploitation allows execution of arbitrary commands with root privileges, resulting in high confidentiality and integrity impacts but no availability disruption (CVSS:3.1 score of 8.1: AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N).
