Poodle SSLv3 Vulnerability and Protection Against its Impact

A Secure business builds trust which is much essential for growth of any company. This is why enterprises make huge investments in security management solutions. To keep business immune from security threats, CTOs and IT managers at organizations are always looking out for new innovative technologies to run the organizations smoothly and keep away any threats. One of the security related risks is Poodle SSLv3 vulnerability.

What is SSLv3 Vulnerability?

In the version 3 of SSL encryption protocol, SSLv3 vulnerability was revealed on October 14th, 2014. Known as POODLE (Padding Oracle On Downgraded Legacy Encryption), it allows the attackers to access the encrypted information like passwords, cookies etc. and lets him access the user’s secured account data on the website.

Who are at the risks of SSLv3 Vulnerability?

POODLE SSLv3 attack can be performed against any website or the browsers that still support SSLv3. As a matter of fact, almost all websites allow SSLv3 connection to support older browsers, but it is not used because there are only few browsers that don’t support the latest TLS versions.

How POODLE SSLv3 functions?

POODLE becomes risky because the SSLv3 Protocol doesn’t verify the padding bytes properly which are sent with the encrypted messages. Later, the attackers replace these and direct them to the maligned destinations. Repeated actions will decrypt more and more bytes and the encryption is deciphered.

POODLE SSLv3 Protection

Completely disabling the SSLv3 support is the best way to avoid any risk related to it. Although many application use better methods for default encryption but still SSLv3 support is implemented as fallout option. Steps should be taken by Server managers, users, data centers, web hosts etc. to disable the obsolete SSLv3 support because a cyber-criminals may force SSLv3 connection if users at both the ends accept it as a method of encryption.

So, always make sure that web browsers never allow SSLv3 as an acceptable encryption method as the consequences can be fatal to the data.
