SSLv3 is enabled in IBM Sterling B2B Integrator. Vulnerability Details CVE-ID: CVE-2014-3566 DESCRIPTION: Product could allow a remote attacker to obtain sensitive information, caused by a design error when using the SSLv3 protocol. A remote user with the ability to conduct a man-in-the-middle attack could exploit this vulnerability via a POODLE (Padding Oracle On Downgraded Legacy Encryption) attack to decrypt SSL sessions and access the plaintext of encrypted connections. CVSS Base Score: 4.3 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/97013 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/A:N) Warning: We strongly encourage you to take action as soon as possible as potential implications to your environment may be more serious than indicated by the CVSS score. Affected Products and Versions IBM Sterling B2B Integrator 5.2 IBM Sterling File Gateway 2.2 Sterling Integrator 5.1 Sterling File Gateway 2.1 Remediation/Fixes None Workarounds and Mitigations Reconfigure to disable SSLv3 and select TLS 1.0 or higher where possible. If using NIST strict mode, TLS 1.2 is already enabled. The following table provides instructions on how to reconfigure secure connection settings that apply to both Sterling B2B Integrator 5.2 and 5.1, except where noted. After making the necessary changes, you will need to stop and restart IBM Sterling B2B Integrator in order for these changes to take affect. If you use: Then do this: Dashboard Disable SSLv3 in your internet browser. See your internet browser help for Map Editor instructions on how to do this.
