Description
The vulnerability allows a remote attacker to conduct a padding oracle attack.
The weakness exists in the encryption library due to a flaw in implementation of a number of deprecated encryption algorithms (Triple DES, AES 129, AES 192, and AES 256, all in CBC mode). A remote attacker can conduct man-in-the-middle attack to analyse the CBC mode padding and decrypt the transport encryption.
Successful exploitation of the vulnerability results in decryption of the transport encryption.
