Description Ján Rusnačko 2016-04-25 10:29:51 EDT

Internally CFME uses AES-256-CBC encryption to encrypt important data before it is saved in the database. This encryption mode is vulnerable to padding oracle attack and CFME does allow attacker to submit forged ciphertexts for encryption and observe the result.
