CVSS: 6.5EPSS: 0%CPEs: 3EXPL: 0CVE-2022-31742 – Mozilla: Querying a WebAuthn token with a large number of allowCredential entries may have leaked cross-origin information
https://notcve.org/view.php?id=CVE-2022-31742
An attacker could have exploited a timing attack by sending a large number of allowCredential entries and detecting the difference between invalid key handles and cross-origin key handles. This could have led to cross-origin account linking in violation of WebAuthn goals. This vulnerability affects Thunderbird < 91.10, Firefox < 101, and Firefox ESR < 91.10. Un atacante podría haber aprovechado un ataque de sincronización enviando una gran cantidad de entradas allowCredential y detectando la diferencia entre identificadores de claves no válidas y identificadores de claves de origen cruzado. Esto podría haber llevado a la vinculación de cuentas entre orígenes en violación de los objetivos de WebAuthn. • https://bugzilla.mozilla.org/show_bug.cgi?id=1730434 https://www.mozilla.org/security/advisories/mfsa2022-20 https://www.mozilla.org/security/advisories/mfsa2022-21 https://www.mozilla.org/security/advisories/mfsa2022-22 https://access.redhat.com/security/cve/CVE-2022-31742 https://bugzilla.redhat.com/show_bug.cgi?id=2092025 • CWE-829: Inclusion of Functionality from Untrusted Control Sphere •
