Logjam is a TLS protocol downgrade vulnerability affecting TLS 1.2 and earlier when a server supports DHE_EXPORT cipher suites. A man-in-the-middle attacker can rewrite a client’s DHE cipher-suite offer to DHE_EXPORT and rewrite the server’s DHE_EXPORT selection back to DHE. Because the handshake does not properly convey the export-grade selection, the client can accept a connection negotiated with 512-bit export-grade ephemeral Diffie-Hellman parameters while believing ordinary DHE was selected.

A Diffie-Hellman downgrade vulnerability referenced in test output; the evaluated TLS 1.2 setup notes common DH parameters but no export ciphers.
A TLS protocol downgrade vulnerability enabling a man-in-the-middle attacker to force vulnerable ephemeral Diffie-Hellman connections to use weak 512-bit export-grade cryptography.
Logjam is a TLS Diffie-Hellman export-grade 512-bit key vulnerability affecting HP-UX Web Server Suite running Apache. HP states it can be remotely exploited to permit unauthorized modification.
A TLS protocol downgrade vulnerability that allows a man-in-the-middle attacker to force vulnerable ephemeral Diffie-Hellman connections to use 512-bit export-grade cryptography.
