Cisco Wireless Residential Gateway Vulnerability

Number: AV14-058
Date: 17 July 2014

Purpose

The purpose of this advisory is to bring attention to a remote code execution vulnerability in Cisco’s wireless residential gateway.

Assessment

Cisco has recently released updates to patch a vulnerability in the web server which, if left unpatched, could allow a remote unauthenticated attacker to exploit a buffer overflow and perform remote code execution. This would allow the attacker to execute arbitrary code with elevated privileges. The vulnerability is due to incorrect input validation for HTTP requests.
