Doc Type: Bug Fix
Doc Text:
A padding oracle flaw was found in the encryption of sensitive information stored within the backend database used by CloudForms. An attacker able to submit forged cipher texts could observe the results of encryption and determine information that could, in turn, lead to the disclosure of encrypted data within the database.

Description Ján Rusnačko 2016-04-25 14:29:51 UTC
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.
