SSL V3.0 Fallback – POODLE Advisory

This is a security advisory on the “SSL V3.0 Fallback – POODLE.”

About the Vulnerability

On October 14th, an attack affecting the SSLv3.0 protocol was disclosed. The attack named POODLE which is acronym for “Padding Oracle On Downgraded Legacy Encryption” allows an attacker with ability to sniff the traffic to rapidly decrypt any communication that uses SSLv3.0 or can be downgraded to SSLv3.0. Any OS, server, client, web application or service that uses communication encryption with SSLv3.0 is vulnerable to this attack vector given that the attacker has ability to sniff the communication at either end.

This attack targets the logic of padding bytes used by SSLv3.0 protocol in order to obtain plaintext from the ciphertext. As most browsers and web servers support falling back to earlier protocol version (known as “downgrade dance”) in case of failed initial SSL handshake. This behavior allows an attacker to target the client/servers that support TLSv1.0 or higher by forcing a downgrade to SSL 3.0.
