The POODLE Attack – SSL 3.0 Protocol Vulnerability (CVE-2014-3566)

Systems Affected

All systems and applications utilizing the Secure Socket Layer (SSL) 3.0 with cipher-block chaining (CBC) mode ciphers may be vulnerable. However, the POODLE (Padding Oracle On Downgraded Legacy Encryption) attack demonstrates this vulnerability using web browsers and web servers, which is one of the most likely exploitation scenarios.

 

Solution

There is currently no fix for the vulnerability SSL 3.0 itself, as the issue is fundamental to the protocol; however, disabling SSL 3.0 support in system/application configurations is the most viable solution currently available.

 

** Updates available: RHEL/CentOS/RPM based OS:

yum -y update openssl

** You MUST disable SSLv3 in all used services (httpd, mail, etc) , The update just prevents the downgrading but the protocol itself is still vulnerable.
