CVE-2015-4000

CVE-2015-4000, low severity (CVSS 3.7): 5 tracked apps concerned, all fixed or indeterminable on their current version.

Severity (CVSS): 3.7
Exploitation: 99.9 %
Tracked apps: 5
Still exposed: 0

Published on 2015-05-21

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.
