CS2107 Padding Oracle Attack
As the encryption is performed in fixed size blocks, padding is usually needed in the last block to complete its length. Usually PKCS7 is used. Padding Oracle Attacks arise due to a vulnerability in the decryption validation process of Cipher-Block Chaining (CBC) encrypted messages. This is not a new. Padding oracle attacks.
