Name of the Vulnerable Software and Affected Versions com.getdropbox.Dropbox app version 100.2 for iOS

Description An issue in the LAContext class for Biometric (TouchID) validation allows authentication bypass by overriding the LAContext return Boolean value to be "true" because the kSecAccessControlUserPresence protection mechanism is not used. This means an attacker could authenticate with an arbitrary fingerprint. The vendor indicates that this is not an attack of interest within the context of their threat model, which excludes iOS devices on which a jailbreak has occurred.

Recommendations For com.getdropbox.Dropbox app version 100.2, consider disabling the Biometric (TouchID) validation feature until a patch is available to prevent potential authentication bypass.
