Inadequate Encryption Strength
In the Procter & Gamble "Oral-B App" (aka com.pg.oralb.oralbapp) application 5.0.0 for Android, AES encryption with static parameters is used to secure the locally stored shared preferences. An attacker can gain access to locally stored user data more easily by leveraging access to the preferences XML file.
CWE-326 - Inadequate Encryption Strength
The software stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required.
