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".
