OTP secret disclosure via capturable setup screen

Published Mar 14, 2023 · Updated Feb 27, 2025

Information disclosure in SAP Authenticator for Android 1.3.0 allows attackers to capture OTPs and setup secrets from the screen. The OTP display and token-setup screens permit capture, exposing the current OTP and alphanumeric OTP secret while a token is configured. Exploitation requires a malicious app on the same device and user interaction; the reported impact is read-only disclosure, not modification or deletion.
