TLS Diffie-Hellman Key Exchange Information Disclosure Vulnerability

  Severity: CRITICAL
  Advisory Date: JUL 21, 2015

  DESCRIPTION

The TLS protocol 1.2 and earlier, when a DHE_EXPORT ciphersuite is enabled on a server but not on a client, does not properly convey a DHE_EXPORT choice, which allows man-in-the-middle attackers to conduct cipher-downgrade attacks by rewriting a ClientHello with DHE replaced by DHE_EXPORT and then rewriting a ServerHello with DHE_EXPORT replaced by DHE, aka the "Logjam" issue.
