Security Bulletin: Vulnerability in Diffie-Hellman ciphers affects IBM Cloud Orchestrator and IBM Cloud Orchestrator Enterprise, and products shipped with IBM Cloud Orchestrator and IBM Cloud Orchestrator Enterprise (CVE-2015-4000)

Summary

The Logjam Attack on TLS connections using the Diffie-Hellman (DH) key exchange protocol affects IBM Cloud Orchestrator, IBM Cloud Orchestrator Enterprise and supporting products shipped with IBM Cloud Orchestrator and IBM Cloud Orchestrator Enterprise.

Vulnerability Details

CVEID: CVE-2015-4000**
DESCRIPTION:** The TLS protocol could allow a remote attacker to obtain sensitive information, caused by the failure to properly convey a DHE_EXPORT ciphersuite choice. An attacker could exploit this vulnerability using man-in-the-middle techniques to force a downgrade to 512-bit export-grade cipher. Successful exploitation could allow an attacker to recover the session key as well as modify the contents of the traffic. This vulnerability is commonly referred to as “Logjam”.
