When was the poodle SSLv3 vulnerability disclosed?
On October 14th, 2014, a vulnerability in version 3 of the SSL encryption protocol was disclosed. This vulnerability, dubbed POODLE (Padding Oracle On Downgraded Legacy Encryption), allows an attacker to read information encrypted with this version of the protocol in plain text using a man-in-the-middle attack.
What does poodle mean in SSL 3.0?
The POODLE attack exploits protocol fallback from TLS to SSL 3.0 to reveal information from encrypted HTTPS communication. POODLE stands for “Padding Oracle On Downgraded Legacy Encryption” and, as the name implies, combines a padding oracle attack and a protocol downgrade attack.
How does the poodle man in the middle attack work?
The bad news is that if vulnerable, a man-in-the-middle attack can be executed to compromise the encrypted session. How Does the Exploit Work? The POODLE threat is a man-in-the-middle attack that forces modern clients (browsers) and servers (websites) to downgrade the security protocol to SSLv3 from TLSv1.0 or higher.
What is the POODLE vulnerability in Oracle security?
This vulnerability, dubbed POODLE (Padding Oracle On Downgraded Legacy Encryption), allows an attacker to read information encrypted with this version of the protocol in plain text using a man-in-the-middle attack.
Is the SSL 3.0 protocol vulnerable to the POODLE attack?
Some Transport Layer Security (TLS) implementations are also vulnerable to the POODLE attack. US-CERT is aware of a design vulnerability found in the way SSL 3.0 handles block cipher mode padding. The POODLE attack demonstrates how an attacker can exploit this vulnerability to decrypt and extract information from inside an encrypted transaction.
Is the SSLv3 protocol still in use?
Although SSLv3 is an older version of the protocol which is mainly obsolete, many pieces of software still fall back on SSLv3 if better encryption options are not available.
