Command Injection in GL.iNet GL-MT3000 Tor Proxy Service Configuration Handler

IdentifiersCVE-2026-12186CWE-77· Improper Neutralization of Special…

CVE-2026-12186 is a remote command injection vulnerability affecting GL.iNet GL-MT3000 devices up to version 4.4.5. The flaw is reported in the replace_country function within /usr/lib/oui-httpd/rpc/tor, part of the Tor Proxy Service Configuration Handler. Improper handling of attacker-controlled input in this function allows crafted data to be injected into an OS command context. The issue is reachable remotely and the available context indicates exploitation does not require user interaction, though low privileges are required. Public exploit details are available.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can result in arbitrary command execution on the affected device in the security context of the vulnerable service. Given the reported CVSS characteristics and command injection nature, this can enable compromise of confidentiality, integrity, and availability on the router, including unauthorized configuration changes, execution of additional payloads, service disruption, and potential use of the device as a pivot point within the local network.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, reduce exposure to the vulnerable Tor Proxy Service Configuration Handler by restricting remote access to the management interface and any RPC endpoints, limiting access to trusted administrative networks only, disabling the affected Tor proxy functionality if it is not required, and monitoring for suspicious configuration changes or command execution artifacts on the device. Because public exploit information exists, prioritizing patch deployment is advisable.

Remediation

Patch, then assume compromise.

Upgrade affected GL.iNet GL-MT3000 devices from vulnerable versions up to 4.4.5 to a fixed release. The provided advisory states that upgrading to version 4.7 addresses the issue. Validate that the device is running a non-vulnerable firmware version after upgrade and apply the vendor-provided fixed firmware through normal maintenance procedures.
