CVE-2024-5657Public exploitNetwork attack vector

Password-hash disclosure via full user serialization

Published Jun 6, 2024 · Updated Sep 3, 2025

Information disclosure in Born05 Craft Two-Factor Authentication 3.3.1 through 3.3.3 allows remote authenticated users to read a password hash. VerifyController::_handleSuccessfulLogin returns the full user model through asModelSuccess after a valid TOTP, serializing the password attribute into JSON. A victim session and valid TOTP are required; the exposed hash can be cracked offline and used to prolong account access.
