| Title | GL.iNet Router 4.8.x RCE |
|---|
| Description | Firewall-management RPC methods accept newline characters in stored firewall fields such as dest_port and dest_ip. Those values are later concatenated into conntrack cleanup commands when rules are changed or removed.
Impact
● Execute arbitrary commands as root.
● Modify persistent router configuration.
● Change DNS, firewall, NAT, routing, or Wi-Fi behavior.
● Read sensitive files available to root.
● Install persistence or alter scheduled tasks.
● Pivot from the router into connected networks.
