Exploit availability: Yes

Description

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to usage of insecure SSLv3 protocol in OpenSSL. A remote attacker can force the current connection between user and server to be downgraded to SSLv3 protocol and then use padding-oracle attack on Cypher-block chaining (CBC) mode to decrypt encrypted communication.

Successful exploitation of the vulnerability may allow an attacker to read encrypted communications in clear text.

Note: The vulnerability is known as POODLE.
