What Is Content Spoofing ? Content spoofing, also referred to as content injection or virtual defacement, is an attack targeting a user made possible by an injection vulnerability in a web application. When an application does not properly handle user supplied data, an attacker can supply content to a web application, typically via a parameter value, that is reflected back to the user. This presents the user with a modified page under the context of the trusted domain. This attack is typically used as, or in conjunction with, social engineering because the attack is exploiting a code-based vulnerability and a user's trust.

What is the POODLE attack? Padding Oracle On Downgraded Legacy Encryption (POODLE) is an issue that affects SSL 3.0. If an adversary can modify network transmissions between the client and the server they can downgrade the SSL connection to SSL 3.0 and tamper with/decrypt data in transmission. The actual problem stems from the fact that the block cipher padding in CBC encryption in SSL 3.0 is not fully verified during the decryption process.
