3.7 (Low) CVSS_V3 - CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N CVSS Calculator

Summary

[none]

Details

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