Belkin N150 path traversal vulnerability

Vulnerability Note VU#774788

Original Release Date: 2014-06-18 | Last Revised: 2015-09-29

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

The CERT/CC is currently unaware of a practical solution to this problem. The vendor had previously indicated that the vulnerability was resolved in firmware version 1.00.08; however, recent reports indicate that firmware version 1.00.08 failed to address the issue and that version 1.00.09 is vulnerable as well. Users should consider the following workaround:

Restrict Access

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