The POODLE attack is a type of security exploit that takes advantage of the way some SSL/TLS implementations handle padding. By manipulating the padding, an attacker can decrypt data that would otherwise be encrypted.
The POODLE attack was first described by a team of security researchers in 2014. The name "POODLE" is an acronym for "Padding Oracle On Downgraded Legacy Encryption."
SSL and TLS are protocols that are used to encrypt communications between two parties. In order to work, these protocols require that both parties have a shared secret key.
Padding is a technique that is used in order to ensure that data is encrypted correctly. It is also used to make sure that the same message encrypted with the same key will always produce the same ciphertext.
Some SSL/TLS implementations use what is known as "padding oracles." This means that they will allow an attacker to submit ciphertexts and receive information about whether or not the padding is correct.
An attacker can use this information to decrypt data that would otherwise be encrypted. This type of attack is known as a "padding oracle attack."
The POODLE attack specifically targets a vulnerability in the way SSL 3.0 handles padding. SSL 3.0 is an older version of the SSL/TLS protocol.
It is no longer considered to be secure, and it has been superseded by newer versions of the SSL/TLS
How does POODLE attack work?
POODLE attack is a type of SSL/TLS attack that exploits the way some browsers fall back to older versions of the SSL/TLS protocol. This attack allows an attacker to decrypt data that would otherwise be encrypted.
The attack works by the attacker injecting malicious code into a web page that the victim visits. This code then forces the victim's browser to use an older version of the SSL/TLS protocol that is vulnerable to the attack. The attacker can then use this vulnerability to decrypt the victim's data.
POODLE attack is a serious security threat and should be mitigated as soon as possible. There are a few different ways to do this, but the most effective is to disable SSL 3.0 entirely. This can be done by setting the SSLProtocol directive in Apache to -SSLv3 or by setting the TLS 1.0 and TLS 1.1 directives in Nginx.
Other mitigation strategies include using a TLS termination proxy or upgrading to a newer version of the SSL/TLS protocol.

What type of attack does POODLE invoke?
POODLE is an attack that exploits a weakness in the SSL 3.0 protocol. By sending specially crafted requests, an attacker can force the server to use the SSL 3.0 protocol, even if it supports a stronger protocol such as TLS 1.0. This allows the attacker to decrypt and modify the traffic passing between the client and server.
Is TLS 1.
0 vulnerable to POODLE? Yes, TLS 1.0 is vulnerable to the POODLE attack. This attack allows an attacker to decrypt traffic that is encrypted using the SSL 3.0 protocol. This attack is possible due to a flaw in the way that SSL 3.0 handles padding.
If you are using TLS 1.0, you should disable SSL 3.0 to protect against this attack. You can do this by setting the SSLProtocol directive to -SSLv3 in your Apache configuration.
What is the CVE of the original POODLE attack?
CVE-2014-3566 (Poodle) is a security vulnerability that was discovered in 2014 in the SSL 3.0 encryption protocol. It allows attackers to decrypt SSL traffic by exploiting a design flaw in the protocol. The original POODLE attack was demonstrated against the SSL 3.0 protocol, but it can also be used against other protocols that use the same encryption method, such as TLS 1.0 and 1.1.
Thereof, can poodle protect you? POODLE is a security vulnerability that was discovered in 2014. It allows attackers to decrypt encrypted traffic by exploiting a flaw in the way that SSL 3.0 handles padding. POODLE can be mitigated by disabling SSL 3.0 support on servers and clients.
