{"id":"UBUNTU-CVE-2022-37660","details":"In hostapd 2.10 and earlier, the PKEX code remains active even after a successful PKEX association. An attacker that successfully bootstrapped public keys with another entity using PKEX in the past, will be able to subvert a future bootstrapping by passively observing public keys, re-using the encrypting element Qi and subtracting it from the captured message M (X = M - Qi). This will result in the public ephemeral key X; the only element required to subvert the PKEX association.","modified":"2026-04-22T15:37:52.667359Z","published":"2025-02-11T23:15:00Z","related":["USN-7317-1"],"upstream":["CVE-2022-37660"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2022-37660"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2022-37660"},{"type":"REPORT","url":"https://link.springer.com/article/10.1007/s10207-025-00988-3"},{"type":"REPORT","url":"https://w1.fi/cgit/hostap/commit/?id=15af83cf1846870873a011ed4d714732f01cd2e4"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7317-1"}],"affected":[{"package":{"name":"wpa","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/wpa@2:2.9-1ubuntu4.6?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:2.9-1ubuntu4.6"}]}],"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"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"hostapd","binary_version":"2:2.9-1ubuntu4.6"},{"binary_name":"wpagui","binary_version":"2:2.9-1ubuntu4.6"},{"binary_name":"wpasupplicant","binary_version":"2:2.9-1ubuntu4.6"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-37660.json"}},{"package":{"name":"wpa","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/wpa@2:2.10-6ubuntu2.2?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:2.10-6ubuntu2.2"}]}],"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"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"eapoltest","binary_version":"2:2.10-6ubuntu2.2"},{"binary_name":"hostapd","binary_version":"2:2.10-6ubuntu2.2"},{"binary_name":"wpagui","binary_version":"2:2.10-6ubuntu2.2"},{"binary_name":"wpasupplicant","binary_version":"2:2.10-6ubuntu2.2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-37660.json"}},{"package":{"name":"wpa","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/wpa@2:2.10-21ubuntu0.2?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:2.10-21ubuntu0.2"}]}],"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"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"eapoltest","binary_version":"2:2.10-21ubuntu0.2"},{"binary_name":"hostapd","binary_version":"2:2.10-21ubuntu0.2"},{"binary_name":"wpagui","binary_version":"2:2.10-21ubuntu0.2"},{"binary_name":"wpasupplicant","binary_version":"2:2.10-21ubuntu0.2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-37660.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N"},{"type":"Ubuntu","score":"medium"}]}
