CVE-2024-6294

Session hijacking via logcat token exposure

Published Jun 25, 2024 · Updated Aug 1, 2024

Information exposure in udn News before 4.20.1 allows attackers to recover user sessions from an Android device's logcat data. The Android app writes the authenticated user's session token to logcat during login without preventing privileged apps or physically connected actors from reading it. Access to logcat through a malicious privileged app or physical device access is required, and the recovered session permits login to the news app and other udn services.
