CVE-2026-11447: GL.iNet GL-MT3000 MTK Backend iwinfo.so iwinfo_backend command injection

Noroxi assessment

Priority: Monitor (action score 8/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1.1% (FIRST EPSS); higher than 67.8% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: GL.iNet GL-MT3000 4.7.
  • Severity is disputed: the assigning authority (CNA) scores it 5.3, NVD 2.1.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to GL.iNet GL-MT3000 4.7 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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".
