POODLE Vulnerability Security Notification

Yet another hacker attack, called “POODLE” is making headlines. Connectria’s security team put together a reference guide for mitigating this risk. Whether or not you are a Connectria customer we hope this information is helpful in keeping your data secure and prevents it from falling into the wrong hands.

The CVE 2014-3566 SSL v3.0 POODLE vulnerability affects servers still running SSL 3.0. It centers on cipher block chaining (CBC) encryption implementations that can allow attackers with a Man-in-the-Middle (MITM) position to view the contents of an encrypted transmission. POODLE takes advantage of the fact that when a secure connection attempt fails, servers will fall back to older protocols, such as SSLv3, in attempt to once again communicate securely with the remote client, which helps prevent further issues. To engage, an attacker who can trigger a connection failure then has the ability to force the use of SSLv3 and attempt POODLE, the newest attack method.

Here are some recommended actions you can take:

  1. Disable SSL 3.0 support or disable SSL 3.0 CBC-mode ciphers. Use the following site https://www.poodletest.com to detect if SSL 3.0 is enabled on the client side (Please visit the site from the system that is being tested) and use https://www.ssllabs.com/ssltest/index.html or http://www.poodlebleed.com.
  2. Implement the proper use of TLS_FALLBACK_SCSV to remediate the forced downgrade issue that is part of the vulnerability.
  3. Check for latest news and information at these corresponding resources:

The POODLE vulnerability cannot be mitigated by a patch.  The mitigation will possibly require a reboot of your system.  Your cloud provider should be performing network scans to identify potential exposure, however you are the best resource for validating that your systems are protected.
