DESCRIPTION

On October 16, 2017, security researchers Mathy Vanhoef and Frank Piessens described vulnerabilities in Wi-Fi Protected Access II (WPA2) by publishing a research paper, "Key Reinstallation Attacks: Forcing Nonce Reuse in WPA2". Certain Vulnerable WPA2 handshake traffic can be manipulated to induce nonce and session key reuse, resulting in key reinstallation by a wireless access point (AP) or wireless client. This allows for an attacker within range of an affected AP and wireless client to execute arbitrary packet decryption, packet injection, TCP connection hijacking, and HTTP content injection.

This vulnerability has the following CVEs assigned:

CVE-2017-13077, CVE-2017-13078, CVE-2017-13079, CVE-2017-13080, CVE-2017-13081, CVE-2017-13082, CVE-2017-13084, CVE-2017-13086, CVE-2017-13087, CVE-2017-13088
