CVE-2011-5053

Published Jan 6, 2012 wi-fi CWE-287

Overview

CVE-2011-5053 is a known-severity vulnerability affecting wi-fi wifi_protected_setup_protocol. It was published on January 6, 2012.

Technical Description

The Wi-Fi Protected Setup (WPS) protocol, when the "external registrar" authentication method is used, does not properly inform clients about failed PIN authentication, which makes it easier for remote attackers to discover the PIN value, and consequently discover the Wi-Fi network password or reconfigure an access point, by reading EAP-NACK messages.

Remediation

Check the references section for vendor advisories and patches from wi-fi. Update wifi_protected_setup_protocol to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
