Detailsinfo

A vulnerability was found in Wi-Fi Wifi Protected Setup Protocol (Wireless LAN Software) (version now known) and classified as critical. This issue affects some unknown processing. The manipulation with an unknown input leads to a improper authentication vulnerability. Using CWE to declare the problem leads to CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. Impacted is confidentiality, and integrity. The summary by CVE is:

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.

The weakness was released 01/06/2012 (Website). It is possible to read the advisory at us-cert.gov. The identification of this vulnerability is CVE-2011-5053 since 01/06/2012.
