However, it is not required if the requests are similar or predictable, see AJAX, the attacker has a one in 256 chance in getting the IV (initiation vector) needed to decrypt the next block.

The first factor is the fact that some servers/clients still support SSL 3.0 for interoperability and compatibility with legacy systems. This attack exploits implementation flaws of CBC encryption modein the TLS 1.0 - 1.2 protocols. Please contact the website owners to inform them of this problem.Look, I’m sorry. But the Qualys Scanner also reports a TLSv1 vulnerability.Can you explain how you detect these or is this a false positive?UPDATE 2012-12-16 14:16 CET:  To answer myself: Today Cisco released a Security notice Question: We own several Cisco ASA appliances, which are known to be vulnerable to Poodle, at least SSLv3. The TLS connection for these sites are NOT terminated on either F5 or A10 loadbalancers.Is anything known about this issue on other implementations or could this be a false positive.I am also seeing QID 38604 detected on several of my sites after a nightly scan but NONE of them checked with SSL Labs manually is showing as vulnerable (POODLE (TLS) No. A POODLE attack is an exploit that takes advantage of the way some browsers deal with encryption. POODLE TLS and Zombie POODLE both exploit server stacks which behave differently when receiving TLS records with valid MAC and invalid (non-deterministic) padding. This means that an attacker would be able to decrypt all the traffic to the server.

I have done nothing to my site and have both TLSv1.0 and 1.2 ciphers enabled. For this reason, it should not be seen as a full mitigation.I have also released my Go based padding oracle scanner on GitHub for scanning outside of IP360. The variant exploits implementation flaws in versions of the TLS protocol, making some servers vulnerable to POODLE, even if they disable SSL. Who is Affected by this Vulnerability? Requests containing that type of data generally have a visual component, so even if the javascript is crafted for a particular site and knows how to move the cookie or credit number to an encryption block boundary, wouldn’t  the browser display some error page returned from the server for every incorrect request?You’re actually really close the purpose is to decrypt sensitive data in the pipe, however, the padding oracle attack doesn’t target anything specific like a auth cookie or CC number. Even though TLS specifications require servers to check the padding, some implementations fail to validate it properly, which makes some servers vulnerable to POODLE even if they disable SSL 3.0. domain.com:8443) - 443 is default You can specify a port number (i.e. In a POODLE TLS attack, TLS alerts signify correct padding length (and therefore MAC). An attacker intercepts the traffic, performing a man-in-the-middle (MITM) attack, and impersonates the server until the client agrees to downgrade the connection to SSL 3.0.An attacker can decipher an encrypted block by modifying padding bytes and watching the server response. The attacker does not need to know the encryption method or key. The Padding Oracle On Downgraded Legacy Encryption (POODLE) attack was published in October 2014 and takes advantage of two factors. The decryption is done byte by byte and will generate a large number of connections between the client and server. wouldn’t the user see rejected requests from the server for incorrect IV values?So POODLE is not a web application level vulnerability getting a cookie is only one thing you can do with it. A padding oracle attack is designed to crack encryption not expose vulnerabilities in the application. In POODLE, the attacker is effectively rolling a 256-sided die and simply waiting for each time in lands on 15 (for AES). A successful attack will use about 256 requests to uncover one cookie character, or only 4096 requests for a 16-character cookie. He holds various professional certifications related to ethical hacking, digital forensics and incident response. The other posts in this series include an overview of Although not POODLE per se, Zombie POODLE is in many ways a resurrection of the well-known POODLE TLS (aka POODLE BITES or POODLE 2.0) attack.

Which is correct?I see the TLS Poodle flaw reported on several of my companies sites. The attack… The "Poodle" vulnerability, released on October 14th, 2014, is an attack on the SSL 3.0 protocol.
