Fingerprint lock bypass via injectable authentication callback
Published Jun 30, 2022 · Updated Aug 3, 2024
Improper authentication in Oxen Project Session Android 1.13.0 allows physically proximate attackers to read data by bypassing its fingerprint lock. PassphrasePromptActivity trusts an onAuthenticationSucceeded callback that Frida can invoke with a synthetic result because unlocking is not bound to biometric-protected data. Exploitation requires physical device access and the ability to instrument the application process; the demonstrated consequence is access to protected user data.
