Design/Logic Flaw

Mahara 16.10 before 16.10.7, 17.04 before 17.04.5, and 17.10 before 17.10.2 are vulnerable to being forced, via a man-in-the-middle attack, to interact with Mahara on the HTTP protocol rather than HTTPS even when an SSL certificate is present...

CVE-2015-2319

The TLS stack in Mono before 3.12.1 makes it easier for remote attackers to conduct cipher-downgrade attacks to EXPORTRSA ciphers via crafted TLS traffic, related to the "FREAK" issue, a different vulnerability than CVE-2015-0204...

Downgrade Attack

The openssl gem is vulnerable to downgrade attacks. A malicious user can signal a protocol with a fallback flag even if the server supports a more secure of TLS, allowing a malicious user to conduct attacks through previously patched vulnerabilities...

LOGJAM: TLS connections which support export grade DHE key-exchange are vulnerable to MITM attacks

A flaw was found in the way the TLS protocol composes the Diffie-Hellman exchange for both export and non-export grade cipher suites. An attacker could use this flaw to downgrade a DHE connection to use export-grade key sizes, which could then be broken by sufficient pre-computation. This can lea...
