{"id":"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":"2026-09-14T03:46:21.715504583Z","published":"2025-02-11T00:00:00Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/37xxx/CVE-2022-37660.json","cna_assigner":"mitre"},"references":[{"type":"WEB","url":"https://cert-portal.siemens.com/productcert/html/ssa-585531.html"},{"type":"WEB","url":"https://link.springer.com/article/10.1007/s10207-025-00988-3"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/04/msg00019.html"},{"type":"WEB","url":"https://w1.fi/cgit/hostap/commit/?id=15af83cf1846870873a011ed4d714732f01cd2e4"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/37xxx/CVE-2022-37660.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-37660"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.w1.fi/cgit/hostap","events":[{"introduced":"0"},{"fixed":"15af83cf1846870873a011ed4d714732f01cd2e4"}],"database_specific":{"cpe":"cpe:2.3:a:w1.fi:hostapd:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"last_affected":"2.10"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["hostap_2_10","hostap_2_9","hostap_2_8","hostap_2_7","hostap_2_6","hostap_2_5","hostap_2_4","hostap_2_3","hostap_2_2","hostap_2_1","aosp-kk-from-upstream","hostap_2_0","aosp-jb-start","hostap-1-bp","hostap_0_7_2","hostap_0_7_1","hostap_0_7_0","hostap_0_6_7","hostap_0_6_6","hostap_0_6_5","hostap_0_6_4","hostap_0_6_3"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2022-37660.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N"}]}
