{"id":"UBUNTU-CVE-2023-52424","details":"The IEEE 802.11 standard sometimes enables an adversary to trick a victim into connecting to an unintended or untrusted network with Home WEP, Home WPA3 SAE-loop. Enterprise 802.1X/EAP, Mesh AMPE, or FILS, aka an \"SSID Confusion\" issue. This occurs because the SSID is not always used to derive the pairwise master key or session keys, and because there is not a protected exchange of an SSID during a 4-way handshake.","modified":"2026-07-07T21:03:20.338260724Z","published":"2024-05-17T21:15:00Z","withdrawn":"2026-07-07T18:54:37Z","upstream":["CVE-2023-52424"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-52424"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2023-52424"},{"type":"REPORT","url":"https://www.wi-fi.org/news-events/press-releases"},{"type":"REPORT","url":"https://mentor.ieee.org/802.11/dcn/24/11-24-0938-03-000m-protect-ssid-in-4-way-handshake.docx"},{"type":"REPORT","url":"https://www.top10vpn.com/research/wifi-vulnerability-ssid/"},{"type":"REPORT","url":"https://www.top10vpn.com/assets/2024/05/Top10VPN-x-Vanhoef-SSID-Confusion.pdf"}],"affected":[{"package":{"name":"wpa","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/wpa?arch=source&distro=esm-infra-legacy%2Ftrusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.0-3ubuntu2","1.0-3ubuntu3","1.0-3ubuntu4","2.1-0ubuntu1","2.1-0ubuntu1.1","2.1-0ubuntu1.2","2.1-0ubuntu1.3","2.1-0ubuntu1.4","2.1-0ubuntu1.5","2.1-0ubuntu1.6","2.1-0ubuntu1.7","2.1-0ubuntu1.7+esm1","2.1-0ubuntu1.7+esm2","2.1-0ubuntu1.7+esm3","2.1-0ubuntu1.7+esm4","2.1-0ubuntu1.7+esm5"],"ecosystem_specific":{"binaries":[{"binary_version":"1:2.1-0ubuntu1.7+esm5","binary_name":"hostapd"},{"binary_name":"wpagui","binary_version":"2.1-0ubuntu1.7+esm5"},{"binary_version":"2.1-0ubuntu1.7+esm5","binary_name":"wpasupplicant"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-52424.json"}},{"package":{"name":"wpa","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/wpa?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4-0ubuntu3","2.4-0ubuntu4","2.4-0ubuntu5","2.4-0ubuntu6","2.4-0ubuntu6.2","2.4-0ubuntu6.3","2.4-0ubuntu6.4","2.4-0ubuntu6.5","2.4-0ubuntu6.6","2.4-0ubuntu6.7","2.4-0ubuntu6.8","2.4-0ubuntu6.8+esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"hostapd","binary_version":"1:2.4-0ubuntu6.8+esm1"},{"binary_version":"2.4-0ubuntu6.8+esm1","binary_name":"wpagui"},{"binary_version":"2.4-0ubuntu6.8+esm1","binary_name":"wpasupplicant"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-52424.json"}},{"package":{"name":"wpa","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/wpa?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4-0ubuntu10","2:2.4-1.1ubuntu1","2:2.6-15ubuntu1","2:2.6-15ubuntu2","2:2.6-15ubuntu2.1","2:2.6-15ubuntu2.2","2:2.6-15ubuntu2.3","2:2.6-15ubuntu2.4","2:2.6-15ubuntu2.5","2:2.6-15ubuntu2.6","2:2.6-15ubuntu2.7","2:2.6-15ubuntu2.8","2:2.6-15ubuntu2.8+esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"hostapd","binary_version":"2:2.6-15ubuntu2.8+esm1"},{"binary_name":"wpagui","binary_version":"2:2.6-15ubuntu2.8+esm1"},{"binary_version":"2:2.6-15ubuntu2.8+esm1","binary_name":"wpasupplicant"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-52424.json"}},{"package":{"name":"wpa","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/wpa?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2:2.9-1ubuntu2","2:2.9-1ubuntu3","2:2.9-1ubuntu4","2:2.9-1ubuntu4.1","2:2.9-1ubuntu4.2","2:2.9-1ubuntu4.3","2:2.9-1ubuntu4.4","2:2.9-1ubuntu4.6"],"ecosystem_specific":{"binaries":[{"binary_version":"2:2.9-1ubuntu4.6","binary_name":"hostapd"},{"binary_version":"2:2.9-1ubuntu4.6","binary_name":"wpagui"},{"binary_name":"wpasupplicant","binary_version":"2:2.9-1ubuntu4.6"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-52424.json"}},{"package":{"name":"wpa","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/wpa?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2:2.9.0-21build1","2:2.9.0-23","2:2.10-1","2:2.10-2","2:2.10-6","2:2.10-6ubuntu1","2:2.10-6ubuntu2","2:2.10-6ubuntu2.1","2:2.10-6ubuntu2.2","2:2.10-6ubuntu2.3","2:2.10-6ubuntu2.4"],"ecosystem_specific":{"binaries":[{"binary_name":"eapoltest","binary_version":"2:2.10-6ubuntu2.4"},{"binary_name":"hostapd","binary_version":"2:2.10-6ubuntu2.4"},{"binary_name":"wpagui","binary_version":"2:2.10-6ubuntu2.4"},{"binary_version":"2:2.10-6ubuntu2.4","binary_name":"wpasupplicant"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-52424.json"}},{"package":{"name":"wpa","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/wpa?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2:2.10-15","2:2.10-18","2:2.10-20","2:2.10-21","2:2.10-21build2","2:2.10-21build3","2:2.10-21build4","2:2.10-21ubuntu0.1","2:2.10-21ubuntu0.2","2:2.10-21
