Public PoCs Turn GL-MT3000 Bugs Into Edge Footholds
Public proof-of-concepts turn four GL-MT3000 bugs into easy entry points on a device that sits at the edge of a small network. The first thing that breaks is the router’s trust in normal settings fields; a crafted value can make it run attacker-chosen commands instead of saving a configuration change.
CSIRT Italia says the exposed flaws are CVE-2026-18601, CVE-2026-18602, CVE-2026-18612, and CVE-2026-18616. Three are command-injection bugs tied to uncleaned input such as filename, Hostname, and public_key, and all four are rated CVSS 9.8. The affected build line is GL-iNet GL-MT3000 4.4.x, version 4.4.5 and earlier.
The practical risk is bigger than one compromised appliance. If the gateway at the edge falls, the attacker is already inside the network it fronts, with a path to other SOHO or small-business systems behind it.
