CVE-2015-4000 Information

Share on:
Feb 14, 2021 cve

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.
