Available Exploits 


All systems and applications utilizing the Secure Socket Layer (SSL) 3.0 with cipher-block chaining (CBC) mode ciphers may be vulnerable to POODLE (Padding Oracle On Downgraded Legacy Encryption) attacks. The SSL 3.0 vulnerability stems from the way blocks of data are encrypted under a specific type of encryption algorithm within the SSL protocol. The POODLE attack takes advantage of the protocol version negotiation feature built into SSL to force the use of SSL 3.0 and then leverages this new vulnerability to decrypt select content within the SSL session.

The Payment Card Industry (PCI) Data Security Standard requires a minimum of TLS v1.1 and recommends TLS v1.2. In addition, FIPS 140-2 standard also requires a minimum of TLS v1.1 and recommends TLS v1.2.
