POODLE

POODLE stands for "Padding Oracle On Downgraded Legacy Encryption." It is a security vulnerability that affects SSL 3.0, a protocol used to secure communications over a computer network. The vulnerability allows an attacker to exploit weaknesses in the way SSL 3.0 handles padding in encrypted messages, enabling them to decrypt sensitive information such as cookies or other data transmitted over secure channels. The POODLE attack works by forcing a target to fall back to SSL 3.
