CVE-2011-5053 describes a vulnerability in the Wi-Fi Protected Setup (WPS) protocol, specifically when using the "external registrar" authentication method, affecting Wi-Fi devices implementing this protocol. The flaw allows remote attackers to more easily discover the WPS PIN by analyzing EAP-NACK messages, which improperly disclose information about failed PIN authentication attempts. This medium-severity vulnerability (CVSS 5.8) has a network attack vector, medium attack complexity, and can lead to unauthorized disclosure of the Wi-Fi network password or access point reconfiguration. While not listed in CISA's KEV catalog and with no social media or media coverage, exploit code, specifically "Reaver," is publicly available on ExploitDB, indicating potential for exploitation.
