Belkin N150 path traversal vulnerability

Original Release date: 18 Jun 2014 | Last revised: 18 Jun 2014

Overview

Belkin N150 wireless routers contain a path traversal vulnerability.

Description

CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') - CVE-2014-2962

Belkin N150 wireless router firmware versions 1.00.07 and earlier contain a path traversal vulnerability through the built-in web interface. The webproc cgi module accepts a getpage parameter which takes an unrestricted file path as input. The web server runs with root privileges by default, allowing a malicious attacker to read any file on the system.

Impact

An unauthenticated attacker that is connected to the router's LAN may be able to read critical system files on the router.

Solution

Belkin advises users to upgrade to firmware version 1.00.08. In addition, the following workaround is available:

Restrict Access

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