CVE-2023-45669 – Improper signature counter value handling in webauthn4j-spring-security

https://notcve.org/view.php?id=CVE-2023-45669

WebAuthn4J Spring Security provides Web Authentication specification support for Spring applications. Affected versions are subject to improper signature counter value handling. A flaw was found in webauthn4j-spring-security-core. When an authneticator returns an incremented signature counter value during authentication, webauthn4j-spring-security-core does not properly persist the value, which means cloned authenticator detection does not work. An attacker who cloned valid authenticator in some way can use the cloned authenticator without being detected. • https://github.com/webauthn4j/webauthn4j-spring-security/commit/129700d74d83f9b9a82bf88ebc63707e3cb0a725 https://github.com/webauthn4j/webauthn4j-spring-security/security/advisories/GHSA-v9hx-v6vf-g36j https://www.w3.org/TR/2021/REC-webauthn-2-20210408/#sctn-sign-counter • CWE-287: Improper Authentication •
