Lifecycle Timeline
3DescriptionCVE.org
A security flaw has been discovered in GL.iNet GL-MT3000 up to 4.4.5. Impacted is the function iwinfo_backend of the file iwinfo.so of the component MTK Backend. The manipulation of the argument device results in command injection. The attack can be executed remotely. The exploit has been released to the public and may be used for attacks. Upgrading to version 4.7 is recommended to address this issue. Upgrading the affected component is recommended. The vendor confirms: "Starting from version 4.7, SDK has added global protection to intercept malicious injection".
AnalysisAI
Command injection in GL.iNet GL-MT3000 router firmware (versions up to 4.4.5) allows a low-privileged remote attacker to execute arbitrary OS commands by manipulating the 'device' argument passed to the iwinfo_backend function in iwinfo.so. A public proof-of-concept exploit is available on GitHub, raising the realistic likelihood of opportunistic abuse. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated session with at minimum low-privilege credentials (confirmed by PR:L in the CVSS vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 6.3 (Medium) is driven by AV:N/AC:L/PR:L/UI:N, meaning the attack is network-accessible, low complexity, requires only low-privilege credentials, and needs no user interaction - a meaningful attack surface for any internet-exposed management interface. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with a valid low-privilege account on the GL-MT3000 management interface (or obtained through credential stuffing against a default or weak password) sends a crafted request to the iwinfo_backend function with a malicious 'device' argument such as 'wlan0; id > /tmp/out' or a reverse shell payload. The unsanitized argument is passed to an underlying system command, executing the injected payload in the router's OS context. … |
| Remediation | The primary remediation is to upgrade GL-MT3000 firmware to version 4.7 or later, which introduces a global injection protection layer in the SDK - confirmed directly by the GL.iNet vendor. … Detailed patch versions, workarounds, and compensating controls in full report. |
