CVE-2020-35455

Account takeover via plaintext credential storage

Published Mar 17, 2021 · Updated Aug 4, 2024

Cleartext credential storage in Taidii Diibear 2.4.0 allows local users to obtain account credentials from Android application data. The application writes usernames, passwords, and authentication tokens in plaintext to Shared Preferences and stores additional sensitive records in a plaintext SQLite database. Exploitation requires local read access to the device's application data, after which the exposed credentials permit full access to the victim's account.
